Code P0305 and P2314
 

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.

Attachment 1603
Attachment 1604

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.

continuity and resistance is good.

Hmmm.....Probably bad PCM.

swap coils from cylinder 3 and 5. disconnect the battery, count to 10 and reconnect.

Does the code switch to 303????

Dont get me wrong....I wasnt trying to be sarcastic or Cynical.......I have honestly found this to be reasonably true, and I have this SAME conversation, probably 3 or 4 times a week.

For the moment, lets get your pulse back...but those "SUPER-DE-DUPER" platinum "Barn Burners"...Ummm....Sparkplugs, are not exactly the best of choices.

Just be lucky your dealing with the "Front" of the motor....:)

So today is a BEAUTIFUL DAY here in Upstate Ny. Decided to look at the Pac one more time with the diagram that Mrs.Djinn-n-Tonic posted. Many thank to you for helping me fined and solved the problem.
Comes to find out I had a BAD wire from PCM to Coil #5. I chekd a 1,3,and they were fine,then looking at 5 and there was my problem. No continuity.

Ooops! Mr. Djinn-n-Tonic....lol. Thank u again. You were rite!

I Love this forum.
