Timingbelt issuses replaced timingbelt now misfire in 1,3,5 coil bank

Problem sometimes is with cheap parts they are bad.Good wires,good plugs,good coils.

have you cleared the codes between fault reads
clean the maf first .....replace the maf if faulty
coil packs ?
injectors

OK, We'll cover the Diagnostic Test Codes (DTCs), starting with the standard definition set by SAE J2012 (Revised December 2007)
DTC P0171 "System Too Lean Bank 1"
DTC P0174 "System Too Lean Bank 2"
DTC P0301 "Cylinder 1 Misfire Detected"
DTC P0305 "Cylinder 5 Misfire Detected"
DTC P0316 "Engine Misfire Detected on Startup (First 1000 Revolutions)"

The "system lean" codes are pretty much telling you that there is way too much oxygen in the exhaust. There is too much oxygen on BOTH sides of the engine, and that is why you are getting codes for bank 1 and for bank 2. Bank 1 is the side where #1 cykinder is located and Bank 2 is the opposite side.

The misfire codes are pretty self-explanatory. #1 and # 5 cylinders are misfiring. The P0316 DTC is telling you that the misfire monitor is detecting a misfire as soon as the engine starts. This tells you that it is a very severe misfire and that the engine does not have to warm up and the car does not have to be driven to detect the misfire.

A misfire can be caused by many things it can be vacuum leaks, bad spark plugs, bad ignition cables, faulty ignition coils, fouled or malfunctioning injectors or injector circuits, blown head gasket, cracked cylinder head, burnt valves, etc.. etc..

However, look at the codes you have. Then look at the firing order for your engine. 2002 Mercury Sable is only equipped with a 3.0L 2V 6-cylinder engine.
The firing order is 1-4-2-5-3-6

Now if you take the firing order and split it in half, stack the two halves on top of each other, it looks like this:
1-4-2
5-3-6

When you look at the firing order this way, you can see that cylinders 1 an 5, 4 and 3, and 2 and 6, are "PAIRED" cylinders. They are exacly opposite in the firing order. Now, the cylinder only fires every second revolution of the crankshaft. With paired cylinders, one of the cylinders in the pair will fire on the first revolution and the other cylinder will fire on the second revolution.

Looking back at your codes, please note that the cylinders that are setting the misfire codes are paired cylinders.

Now the coil pack for your ignition is actually made up of three coils. Each coil fires a set of paired cylinders. If you look at the top of the coil, it will usually be marked with the cylinder numbers that each coil tower is supposed to connect to. The coil will look just like the firing order split and stacked as above.

With all of this said, I would say that it is VERY LIKELY that your misfire codes are being caused by a defective ignition coil.

The lean codes are a little different.

These are USUALLY caused by vacuum leaks which allow too much air into the engine that is not getting measured by the Mass Airflow (MAF) sensor and causes the engine to be getting too much air and not enough fuel (running lean).

I would take a good look at all of the vacuum hoses and lines. Ford is notorious for getting holes in the rubber parts that connect the PCV tubes.

If you do not find any obvious reasons for a vacuum leak, then you may want to fix the misfire codes, reset the computer memory, and drive the vehicle to see if the lean codes come back again. The misfires COULD be the cause of the lean codes. In a perfect world, this is not supposed to happen because the misfire monitors setting codes will not allow the oxygen sensor monitors to run and set lean codes. However, I HAVE seen cylinder misfires that have caused lean codes.

I hope this helps you to figure it out. Good luck!

As of 1996,all cars sold in the US were required to have an OBD-II computer interface port.

Maximas with the VE30DE and VQ30DE engines use a distributorless ignition system that is controlled by the Engine Control Module (ECM). The ECM receives a signal from the crankshaft sensor (the CPS - Crankshaft Position Sensor), and processes the signal based on inputs
from other various engine sensors, including the Oxygen sensor.
(this is the role of the O2 sensor in ECM operation).
Then the ECM sends signals to each of the individual coils in the proper firing order.
This system is more efficient than a distributor, and has fewer moving parts. The high voltage coils are directly attached to each spark plug, allowing a higher energy spark within the cylinder. A high energy spark means a faster, more thorough burning of the air/fuel mixture, which produces more power and lower emissions.


SECONDARY SPARK TEST - works for all cars, including Maxima.


1. Remove the spark plug.

2. Install the spark plug to the ignition coil/coil pack, then attach the coil wiring.

3. Ground the plug at a good ground location on the engine.

4. Crank the engine and check for spark.

5. If spark occurs, the ignition system is functioning properly.

6. If no spark exists, test the ignition coil/coil pack, power transistor and related wiring.

----------------------------------------------------------------------------------------------------------------------------
HEI Ignition Spark test - works for all cars, including Maxima.

The next level test you may want to try is a HEI (high energy ignition) spark tester kit. Cost is
about $30 at most auto parts stores. Harbor Freight Tools sells a chinese equivalent for about $16.
Place the spark tester on each of the spark plugs, and watch as the little light in the tester will
light up each time the spark plug is fired by the computer. You can actually see weak or
intermittent sparking as the motor runs - you can tell by the relative strength of the light as
you compare the intensity and duration of the light across all 6 cylinders.

If your problem were the alternator (or its built-in voltage regulator), your battery would not be
getting a proper charge, and you
wouldn't be able to start the car after a drive, since the battery would have been drained during the
drive - normally, the alternator will both charge the battery and run all electrical
features of the car during a drive.

To test your alternator, place your DMM (digital multimeter) across the battery terminals while the
car is running - it should read 13.5VDC to 14.5VDC. With the car off, you can test your battery
voltage with the same DMM - it should read 12.65 VDC (for a fully charged battery).

Alternatively, you can take your car to Advance Auto Parts, AutoZone, or Pep Boys, and they'll
attach their "charging system tester" to your car and give your car a nice test for free.
I do this with my customers' cars just to get that nifty printout of the problem. Its nice
to show a vehicle owner somethng in black & white when I'm recommending a new charging
or ignition system component (some of which can be a bit pricey).

I wouldn't worry about the 02 code it will clear when you replace the coils. to be positive that the coils are bad, swap them with another cylinder and see if that cylinder misfires. 90% of the time it's the coil. Let me know

according to this fault codes first mark ignition coils
3 ---------------- 6
2 ---------------- 5
1 ---------------- 4
RB-------------LB
this right banks and left bank, please remove Ignition coils with lids and spark plugs from right bank and swap with left bank, if fault code change as
P 0304 Cylinder 4 Misfire Detected
P 0305 Cylinder 5 Misfire Detected
P 0306 Cylinder 6 Misfire Detected
You can Identify it's a faulty ignition system then next swap ignition lids from ignition coils be careful each coils have two lids one short and other long bit deference and when you remove and fix it to the car keep in mind correct order because each coil two different fire for two spark plugs don't mix up, if you mix it can create the fault code.if you detect any fault ignition coils or spark plugs or lids replace that and also whether god or bad recommend to replace spark plugs, find the right that's most important thing, if this way couldn't found the any ignition fault next step is check fuel presser, when the engine running fuel presser must be around 4.5 bar without engine running must be 4 to 6 bar if the fuel presser too low need to check two different things one is fuel pump other is fuel injectors, in this case you can swap injectors from right bank to left bank and find is the injectors leaking, if not leaking faulty fuel pump.is this information helped you? if yes please leave a comment,

P0171------ system too lean bank#1
Po174------ system too lean bank#2
For these 2 codes, try cleaning the maf sensor (mass air flow), that is mounted in the big black hose that goes from the air filter housing to the throttle plate, if it is dirty, that will cause those 02 sensors to send a signal to the computor to lean the air fuel mixture. If cleaning it doesn't work, the sensors will probably need changing.
P0300---- Random/multiple cylinder misfire
P0316---- Cylinder misfire at start up---- first 100 revolutions.
On those 2 codes, you have to do some testing to find out why there is a misfire.
Possible causes:
dirty/malfunctioning injectors
weak coil pack
fowling spark plugs/wires
Low fuel pressure

PO135 = Upstream Heated Oxygen Sensor Heater (HTR 11) circuit (Bank #1)

P1131 = Lack of upstream Heated Oxygen Sensor (HO2S 11) switch, sensor indicates lean (Bank #1)

P0305 = Cylinder #5 Misfire detected

It looks like you have two separate issues happening. Bank 1 would be the left side of the engine if you were standing in front of the truck looking at the engine. The "upstream" oxygen sensor will be on the exhaust pipe coming from the bank one side of the truck IN FRONT of the catalytic converter. From the codes, it appears that the upstream sensor has gone bad, but the oxygen sensor behind the catalytic converter, or "down stream" is fine.

The misfire on cylinder 5 on the right side of the engine, 2nd one from the front, could be something as simple as a fouled spark plug or a coil malfunction.

To identify if it is a bad coil, swap the #5 cylinder coil with another coil, and see if the misfire follows the relocated coil.

Have your ignition coils replaced
