SOURCE: my 1996 Gmc K2500 with a 7.4l is miss firing. runs

Very good chance that it's bad fuel injectors and/or fuel pressure regulator. Very common with the 96-2000 L29 motor (Vortec 7.4L)
Replace with better injectors, the OEM ones are NOT WORTH cleaning. Go to http://www.fullsizechevy.com/forums/general-discussion/technical-maintenance/213662-96-99-454-vortec-owners.html

Why am I getting code # P 0308


I have your vehicle as a 97 Ford Expedition...Is this correct? Reason I ask is that Ford uses Coil-On-Plug and you said "I changed the wires"...Which would mean all eight coils were changed...P0308 is telling you the ECM is seeing a fault on cylinder #8...I would strongly suspect a bad coil for that cylinder...Question; Did you change all eight coils? If not change #8...saailer

1996 Lincoln Mark VIII has engine misfire on number 8 cylinder


THis is the same that P0308 fault code when "check engine" light turn on. A P0308 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #8.

Symptoms may include:
the engine may be harder to start
the engine may stumble / stumble, and/or hesitate
other symptoms may also be present


A code P0308 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer

Possible Solutions:
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are symptoms such as 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 wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day

4.7l V-8---error code P0308 is being displayed---about a year ago, I replaced the plugs and all 8 coil packs---thanks


Hi. This P0308 code means that the the PCM has detected that one of the engine's cylinders are not firing properly. In this case it will be cylinder Number 8.

A code P0308 may indicate that one or more of the following has occurred:

1 Faulty spark plug or wire
2 Faulty coil (pack)
3 Faulty oxygen sensor(s)
4 Faulty fuel injector
5 Burned exhaust valve
6 Faulty catalytic converter(s)
7 Running out of fuel
8 Poor compression
9 Defective computer

If there are no symptoms, the first thing to do is to reset the code, with a code reader, and see if it comes back. If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the affected cylinder and plug/coil assembly. 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 wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs-COP-). In some cases, the catalytic converter has collapsed. If you smell rotten eggs in the exhaust, your converter may need to be replaced. I've also been told several times that the problem in this case could be a faulty injector at that cylinder 8.

P0308 cylinder 8 misfire detected? How to repair?


Fuel injector cleaner commonly has a low success rate, and will not help if it's more than one cylinder that is missfiring. The fact that you have a "rattle" noise, leads me to beleive the engine is not receiving fuel on one or more cylidners. If it is all the cylinders, than the fuel pump may be the culprit, or the fuel pump circuit. But if only one cylidner is missfiring than it is a possibly an injector. A code P0300 refers to all cylinder missfires, and any code between P0301-P0308 distinugiushes a particular cylinder.

Misfiring
1- a general electrical tune-up (spark plugs, wire set, cap & rotor) is a basic start to cure this issue. Wiggle the dist shaft while you are in there, if you have one.
2- Then a good carbon cleaning / throttle-body cleaning.
3- Vacuum leaks at any of the hoses that connect to the Intake manifold; especially the MAP sensor connection.
4- If that does not help then the O2 sensor could be bad or drifting.
5- Funky coil/coil-packs
6- Theoretically a microsecond glitch in either the cam or crank shaft sensors would cause this, but I am not aware of this as a typical cause.
7- Lastly a funky PCM but again it is not common for this to cause miss-firing.

Note for the V8 then also:
a) bad erg valve (this dilutes the combustion gases and hence raises the combustion temp
b) a leaky plenum/Intake manifold gasket. Leaking Intake gasket symptoms

Also can check the TSB 18-48-98 Ignition System Cross Fire/Secondary Ignition Wire Induction (Complete Version )

Hope help with this (remember rated this). Good luck and have a nice day.

You didn't specify where you put the seafoam (oil, gas tank, vacuum lines etc) It's very possible that the fuel filter needs changing and the spark plugs may very well be fouled. After seafoaming a car it's a good idea to really open it up to burn off the foam and residue.
