Hello! Please send the year of the vehicle and I'll send an action plan to solve the problem...Do you have a mulitimeter and a wee bit of experience using it? Included in the plan will be test procedures (not difficult) which require a meter.....

I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867
Hello! Here is a short list of non-year specific checks...Test procedures are year-specific and as soon as I know the year of your vehicle I'll send them (if necessary)...
The cause of these multiple faults is a fuel/air mixture problem...The effect is Oxygen Sensor P codes..
#1.. You most likely have a vacuum leak. When you have a vacuum leak the computer (PCM) reads air intake volume at the Mass Air Flow Sensor (MAF)...The O2's are reading a lean condition so the PCM compensates by adding fuel...This is called "fuel trim" (running rich and fouling plugs)...Check all vacuum lines...Check the tube that runs from the Positive Crankcase Ventilation (PCV) valve to an elbow in either the intake manifold..This elbow has a history of breaking...
#2...The Mass Air Flow (MAF) sensor may be fouled...If you are using an after market air filter the oil tends to foul the MAF...The MAF is in between the throttle body and the air filter outlet...Pull the connector and see if there is any improvement...
#3...Pull the spark plugs and inspect for fouling...Clean and reinstall...Don't replace...
#4...If the ground wires from the - battery terminal to the chassis, and the engine block are corroded, rusted or broken the sensors will malfunction...Set meter to X1 ohm scale...Place one meter probe on the center of the - battery terminal...The other to bare metal chassis (fender bolt)...Record reading...Move probe from chassis to bare metal on the engine block...Record reading...Send results...
Guru...Saailer
Hello! I have been out of town...I'm a Ford expert...I'll talk you through a series of procedures to solve your vehicle's problem...The resistance readings are perfect...First of all the O2 sensors react to a fault and in most cases are not the cause but an effect...The O2's are reading a fuel mixture fault...Hold off on the fuel filter and lets start with the Mass Air Flow (MAF) and vacuum lines...Disconnect the connector on the MAF...It is located between the air filter box and the throttle body...See picture below...It has a six pin connector...Start the engine...Do you notice any improvement in the way the engine runs? On the under-side of the hood is a vacuum line diagram...Follow each line looking for soft, broken or disconnected vacuum lines...This looks like a vacuum problem...Let me know the results...The plan is to localize...Without spending any money...Send a comment with results..PS....Pull out the PCV valve and shake it...Does the ball rattle?
Hello Jorge! Please tell me the wire colors that are in the plug that you disconnected...The one that you say controls the air inlet...Saailer
Hello! The Mass Air Flow (MAF) sensor is also the Intake Air Temperature (IAT) sensor...It's looking like it may be the problem...Disconnect the inlet tube clamp...Loosen the other side of the MAF and remove it...Be careful it's delicate...Take a trip to Radio Shack and buy a product called Deoxit...About $15...There are two small spray cans...Use the cleaner and spray (not much) into both ends of the connector pins...Also spray inside the MAF sensor...Reinstall and test the engine...Plug in the other connector you removed (I do not know what this one is until you tell me the wire colors)...Send a comment...saailer
Hello! The device that you disconnected is the Throttle Positioning Sensor (TPS)...After you clean and reinstall the MAF, we will perform a test procedure...Do you have a multimeter? If so set the meter to read 5 volts DC...Plug the TPS connector back in...Using 3 safety pins push the point into the rear of the in-place connector into the following wire colors...Note; there are two Yellow/White wires...Look at the connector to identify pin numbers...The Yellow/White wire we want is pin # 1...Push one safety pin into that wire...Another into Pin # 3 a Pink/Orange...Push the third safety pin into Pin # 4 a Gray/White wire...The colors are hard to read because they age...See a picture of the TPS below...
Connect the + meter probe to the Yellow/White (pin 1)...The - probe to the Pink/Orange (pin 3)...Turn the key to ON...do not start...Record reading...It must be less than 1 volt (.85)...Move the + probe to Pin 4...Gray/White wire...Record reading...Must also read less than 1 volt (.85)...Send results...Saailer
Hello! Yes...reassemble..Plug everything back in...Did you receive the procedure to test the TPS? Do you have a volt meter? go ahead and test the TPS...When you said the engine would idle with the TPS unplugged, that was a giant step forward...The TPS is more than likely the bad component...That's why testing it is important...If the test gives you any trouble just contact me...I am here!...saailer
Hello Jorge!...Put everything back together...Test the TPS with the key in the ON position...Don't start the engine...Follow the procedure that I sent you...saailer

Hi and welcome to FixYa!
As a first course of action I strongly suggest that you replace the MAF (mass air flow) sensor first. Once replaced there will surely be a big change on engine performance.
Please do check the vacuum hoses too for any loose or worn hose can cause the car to misfire. Please replace worn hoses.
You may try to add an additional body ground to make the current flow smoothly.
Hope this helps and thank you for using FixYa! Have a good one!
Several thnigs to check there; review all informastion disponible to do it and solve this...
P0356 - Ignition Coil F Primary/Secondary Circuit Malfunction
The ignition signal from the Powertrain Control Module (PCM) or Electronic Control Module(ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- The engine may be harder to start
- Engine hesitation
Possible Causes:
- Open or short in the ignition coil circuit
- Ignition coil circuit shorted to ground
- Ignition coil connector
- Damaged ignition coil
- Damaged PCM or ECM
Possible Solution:
- If damage, repair ignition coil circuit
- Replaced ignition coil
- Replaced PCM or ECM
------------------------------------------------------------------------------------------------------------------------------------------------
P0152 - O2 Sensor Circuit High Voltage (Bank 2 Sensor 1)
The heated oxygen sensor 1 is placed into the exhaust manifold. It
detects the amount of oxygen in the exhaust gas compared to the outside
air. The heated oxygen sensor 1 has a closed-end tube made of ceramic
zirconia. The zirconia generates voltage from approximately 1V in richer
conditions to 0V in leaner conditions. The heated oxygen sensor 1
signal is sent to the ECM. The ECM adjusts the injection pulse duration
to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs
near the radical change from 1V to 0V.
Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- High Fuel Consumption
- Excessive Smoke from Exhaust
Possible Causes:
- Harness or connectors (The heated oxygen sensor 1 heater circuit is open or shorted.)
- Front Heater oxygen sensor heater (Bank 2) may be faulty
Possible Solution:
Replacing the O2 Sensor 1 usually takes care of the problem
------------------------------------------------------------------------------------------------------------------------------------------------
P0174 - Fuel Injection System Too Lean Bank 2
With the Air/Fuel Mixture Ratio Self-Learning Control, the actual
mixture ratio can be brought closely to the theoretical mixture ratio
based on the mixture ratio feedback signal from the heated oxygen
sensors 1. The ECM calculates the necessary compensation to correct the
offset between the actual and the theoretical ratios.
In case the amount of the compensation value is extremely large (The
actual mixture ratio is too lean.), the ECM judges the condition as the
fuel injection system malfunction and light up the MIL (2 trip detection
logic).
Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Excessive Fuel Consumption
Possible Causes:
- Intake air leaks
- Front Heated oxygen sensor may be faulty
- Injectors may be faulty
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Mass air flow sensor may be faulty
- Incorrect PCV hose connection
Possible Solution:
Dirty air filter of faulty air flow sensor are common causes of the problem.
------------------------------------------------------------------------------------------------------------------------------------------------
P2197 - DODGE - Sys Too Rich at Hier Load Bank1
Means that the O2 sensors on each bank are seeing WAY
too much oxygen in the exhaust gas. In normal operation the signal from
the O2 sensors should swing back and forth between rich and lean.
Your sensors are locked on lean.
Those codes are the same as P0174 (and P0171). Sounds like you have a
vacuum leak somewhere. Most common place is the PCV elbow where it
connects to the throttle body adapter.
------------------------------------------------------------------------------------------------------------------------------------------------
Hope this helps; keep in touch.
From looking at the code read out iam surprissed it still runs to be honest,i have a funny feeling here you need a new ECU ?iam wondering if its developed a fault like being full of water ,now i do not know what year this vehicle started using a chipped key but i would try a scrapyard for a accident damaged vehicle and take the lot ,chip in the key ,transponder and transponder control box if fitted and the ECU ,if its a early one then the transponder reader will require the dash to be taken out to get at it
I'm going to be up front and honest with you in this. You have way too many codes which tells me you either have a faulty ECM or one major problem. It almost sounds like someone put sugar in your gas tank. The best course of action for you would be to take the vehicle to the dealer because they have the computers to simulate and isolate all those. The only other time I have ever seen this was when someone submerged their vehicle in a lake.
Hi
What year is the vehicle? this is a gas powered vehicle? not diesel yes?
please clarify, sounds like more than one fault but some faults can create others.
Get back to me,
Regards
Dan
Hi
I may be able to help but I need the model year of the vehicle, let me know if you are still having problems.
Regards
Dan
Hi thank you got the info,
do you think i need to replace the o2 sensor or tps on my moms 2000 f-150 that has the 4.6 liter motor in it when you start it it will reve up like someone is pushing on the gas pedal and letting go no matter if it is in park drive or reverse and it will not stay running and now it has gotten to where it ill not start please email me at [email protected]

There are few possibilities that can cause engine misfire
issues. It can be issue with spark plugs or faulty spark plugs. Also get the
compression test done for cylinders. If any of cylinder shows low compression
then required, then that particular cylinder will cause misfire.
Also get obd codes scanned, the error code will let you know
which cylinder is misfiring or all cylinders are misfiring.

FORD expert please take note of engine 4.6 with 110k F15o model 2004
I really need to receive the advise of an expert who can set me up in the less expensive path to repair this engine. Please refrain to make any comment that is not pertinent to the sequence of task to repair this engine.
PS: To much job for a "Dealer's mechanic", they didnt take it. Their solution is to replace engine
This is a 2004 STX F150 that had been repo. Would any FORD expert looking at the codes set me up with a series of task to repair this engine? Please!. Refrain any other comment but the sequence of repair tasks. If you need more info look further on the codes. Please give me a TO-DO plan. Not any other comments. Please
FORD Expert: Please prepare for me the most common sense,less expensive, TO-DO list to repair this engine. I had purchase it from a Repo. If you have access to a more descriptive explanation and probable cause of trouble codes please analize them and set me up in the path to repair it. Thanks
Please set me up with a TO-DO list of repairs in the less expensive path.
Thanks
Thanks!.
I notice the probable cause on 5 codes is related to fuel pressure and a sensor at bank 2 sensor1.
Should I change fuel filter, then MAF then OS?. How can I make engine idle?. There is a electrical failure at coil #6 and is coherent with the not firing of coils at driver side, should all this be related to the computer? If it is so, how I can have the computer flashed? If I can inexpensibly have the computer reset, I rather do that becouse I suspect that before repo somehow they mess the computer system. Please forgive my ignorance and help me out, consider me as a " know nothing" repair man who desperatly needs a plan to start working out a solution.
Thanks again, I am looking forward to heard from you. Thanks
I had just make the resistance measure. between negative terminal on the battery and intake block: 1.8 Ohms, Between negative terminal and front end frame bolt: 2.7 Ohms and between negative terminal and a bolt holding the evaporator to frame: 5.9 ohms. Are this acceptable?. Let me know
Thanks.
After disconnecting the MAF I notice a little improvement (respond to acceleration), can't make idle anyway.
I disconnected the device that controls the opening of the air intake (is the ECM, isn't it?, the accelerator pedal is not active) then idles!.
How can I make it stay idling, that's all I want for now!
Thanks. Look forward for your help!

2 are yellow/white, orange, sky blue
Woulkd i be better off reassembling the intake system?
I had not find any broken,misplaced, or wear off hose.
Mr Saalier,
Would I be better off disassembling intake system and assembling back after checking each component?. Can I check voltages at each component with engine off.?
