SOURCE: Check engine light

A multi misfire may mean that one or more of the following has happened:
Faulty spark plug or wires, Faulty coil (pack), Faulty oxygen sensor(s), Faulty fuel injector(s), Stuck/blocked EGR valve / passages, Faulty camshaft position sensor, Defective computer.

The engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wire, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the the problems were faulty fuel injectors. 

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.

Good luck and hope this information helps, keep me posted, be glad to help you get the truck running 100% again. Not sure if your running a K&N air filter, and if you are there may be a flim of oil on the MAF sensor that is making you run lean. You may want to spray down the MAF sensor with a can of MAF cleaner.

Okay, you either have to get some really expensive aftermarket motor and transmission mounts, or go with OEM from dealer. I did both. you MUST make sure you follow the Haynes or Chilton's manual on setting the engine and transmission at the right degree of rotation, then tighten all anchor bolts to 89 ft-lbs.... i did this and it reduced my vibration tremendously.

Go take it to the dealer you should still have a full warranty. If you want to try and do it your self you could void that warranty.

SOURCE: rough idle, backfire on acceleration

check everything you can under the hood your air intake system all of it especially make sure all clamps are tight .. and make sure all vacuum hoses are good and not cracking or broken or just loose . you might run a little fuel cleaner through a tank of gas too cleaning the engine fuel system up some. just a few ideas..

Hi! When replacing the plugs and wires on this model be sure there is no oil in spark plug wells. You will notice the oil on the plug wire boot when removing it. If there is any oil on any of the boots the valve cover gasket and spark plug tube seals will need to be replaced or the misfire code you mentioned will return. Hope this information helps!

The car does have a maf, but it is rarely the cause of rough idle. Rough idle is usually caused by vacuum leak, pvc issues, or idle air control valve. What does it do, specifically, and is the engine light on?

Engine surges at 2300RPM

The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

MY 97 yukon has Rough idle, loud knocking at high torque, and oil pressure goes from 40psi to 0psi. what do you think is the problem?

Checking oil level won't tell you anything

You need to put a mechanical gauge on
the motor,you can't go by the dash for accuracy

You could have many things that need to be
done preventative maintenance wise before
you even start to diagnose the couple of current

Dash Check Lights?
Driven for two years & never worked on?

We can't guess,you need a repair shop to
give you the solution

I have a Ford Escort 2000 year model. It has a very poor idle. I checked the codes and it showed p0171 p0304 and p1131. I replaced the plugs, wires and the throttle position sensor. The car drove...

The PO 304 ---is a misfire code for cyl #3, just a code

The PO 353 --- is a misfire code for cyl#3 that refers you
to PO 350 which is an undetermined Primary or Secondary
Malfunction You can not have 300 & 350 codes on the same vehicle

The PO171 -is a Lean O2 Code for Bank 1 most likely from
a misfire yet to be determined

The PO 1131 ---Lack of Switching ,lean trying to correct
for over rich condition

Personally I think anyone that uses 10 oz of anything,
in an 16 to 18 gallon fuel tank is wasting their money
There has never been any mfg recommend injector cleaner
In a ford they say not to use it,as it will damage the pintel coating,
which I doubt,still useless product

Did you clean the MAF Sensor

Continue to check for leaks,including
the EVAP System Hoses & Components

I would scope the O2 Sensors,you won't have
a scope & I don't care for a meter, as you don't
see the switching counts or time if they are old & slow

At 100,000 miles, change the ones closest to the engine

For a 40 mph issue under the slightest of vacuum load
check the Egr Valve,unplug hoses,plug them & road test
up hill

Do all your egr & coil testing on a hot day & up hills,
easy on the gas to load the engine some

The misfire codes you get on a ford are only correct about
2/3 of the time & you disregard almost all the misfire ones
You may have to walk 1 new coil until you get to the bad one

Your real issue is the idle problem
Check all vacuum items
Be nice if you could Smoke Test everything
& end that exercise

Check the cam timing before you spend days
going into the belt area

You could use a scanner to look at data,don't know if
you know anyone with one at work

Car seems to idle rough. almost dies then the car revs above normal to compensate. check engion light is on. and for some reason the traction control light comes on when car is running rough.

you need to have an OBDII code scanner to read the error codes or codes for the check engine light being on. sounds like the mass air flow(maf) sensor is the culprit. also possible is either the throttle position sensor(tps) or idle air control(iac) valve. the OBDII code scanner will tell you in a PXXXX error code to help you pinpoint the problem. (the XXXX is the numeric error code and the P stands for powertrain.
