Misfire cylinder #5
New coils,new injector,alternator,Camsensor,Cranksensor.......Wh at else???

 

Compresson test.

 

Had a compression test and that's ok.

 

Year????? Engine size????

Why no mention of Spark plugs being replaced???? I cant believe anyone would diagnose a misfire without checking the plugs FIRST. At very least, the one on the affected cylinder.

#1......You CANNOT use aftermarket Ignition coils...The resistance is different...You MUST use the proper MOPAR coil.

#2,,,,,,Champion Spark plugs are a MUST......No bosch, no Splitfire, no E3's , No Autolites.

The system was designed to work around what the factory used. any deviation WILL WREAK HAVOC.

 

I second that

 

The year is 2005. Yes did replace all the spark plugs with NGK Laser platinum. It's 3.5 and brand new coils from the Dealer "SIR". And BTW theres no Negtive pulse.

 

There's no negative pulse on cylinder #5.

 

Ahh...Thats different. You are either looking for a wiring problem, or a Bad PCM.




You need to check wiring continuity and resistance between pin 2 of connector c2, and the #5 coil.

 

#2,,,,,,Champion Spark plugs are a MUST......No bosch, no Splitfire, No Autolites.

Thanks. Good little nugget of info.

 

I was just cking the wires and there fine. But something caugt my eye. When I was chking the negative pulse it was there then it just went away. Came back and away again. Just for a few seconds. The cars starts fine.
