SOURCE: 2000 CIVIC System too lean Cylinder 3 and 4 misfire Deteced

  1. P0171: This means that the oxygen sensor has detected a lean air-fuel ratio. This can be caused due to a vaccuum leak or a problem in the HO2S circuit or the HO2S (Heated Oxygen Sensor) itself. (Bank one Sensor one). This is commonly located along the exhaust pipe. It could also be a bad Mass Air Flow sensor or a bad Engine Coolant Temperature sensor. Diagnostic checks will be needed to be carried out to be verified though
  2. Well as for the other codes, it means #3&4 cylinders are misfiring. It is a possibility that the P0171 code mite have caused the others to show up. I can be wrong though. But it is a strong possibility. If the air fuel mixtue is too lean indeed, mis-firing will occur, unless it is an actual electronic and not a mechnical problem. By the way, when these codes appear, how is the engine's performance. Does it remain the same or behaves poorly?

SOURCE: 2002 jeep cheroke misfires on cylinder #4

Check intake gasket and vecuum hoses near intake runner #4. To do this spray carb cleaner at parting line between manifold and block while engine is running. If leaking rpm will dramatically change. A leak will lean out that cyl and cause misfire

SOURCE: Hi, I have a 1997 Porsche

misfire :-------- try checking your 02 sensors /fuel pump and filter.

for 51 cylinder misfire :---
Change the coil. Period. Very easy to remove from the vehicle if it's a 4 cyl. Follow that spark plug wire from the spark plug to the other end. What it's attached to you should replace
for 54 cylinder 5 misfire :---First you have to eliminate the most obvious problems, like spark plug and spark plug wire. If you replace those and you still have a misfire, then it's a good idea to look for a vacuum leak in the intake manifold

2006 jeep liberty 3.7 is not getting no gas to cylinder, injector is new, its got fire to the plugs but #2 cylinder is misfiring, we used a test light on injector and injector is not working


What kind of test light did you use? A noid? Is it the injector that's not working, or the computer that sends the signal? Are you getting battery power to one of the injector terminals when the key is on?

I changed my spark plugs and afterwards the chech engine light came on. the jeep runs great. what can make that happen?


IT could be something such as a loose plug wire.The best advise I can give you is to take your jeep to your local auto parts store and have them pull the codes out of your on board computer.This will give you an area that you can concentrate on to make the necessary repairs to get your check engine light to go out.

1999 jeep cherokee 6 cylinder engine light


1.Plugs
2. Vacuum leak
3. Injector fault
4. High or low fuel pressure.
Thats the list of things to check.
This is a #3 cylinder misfire.
There is also TSB about #3 injector needing added heat protection. This could definitely be the cause. I start at plugs and go from there.
Hope this helps.
Thank you,
Lee

P0303 means misfire on number 3 cylinder. It could be a spark plug, spark plug wire, coil pack, or maybe fuel injector. What ever it is, the number 3 cylinder is the problem.
