So My 2000 XJ is misfiring and triping the check engine light it was flashing too. The Jeep ran fine the night before and was about 75 degrees when I tried to start it. The codes are p0352 (Ignition Coil B Primary/Secondary Circuit Malfunction), p0300 (Random/Multiple cylinder misfire), p0302, p0305 (cylinder #2 and cylinder #5 misfire). I have a newer coil installed only a few months old. Spark plugs are about the same age. I still have my old coil which I swapped in thinking it was the coil but with the same problem. My question is would the coil be the first place to look and how do you test it by itself with same a multimeter? If its not the coil what could another possible cause be? I am leaning towards bad pcm or wiring to the coil. Any ideas would be great thanks.

 

use the search button and look for misfires there is alot of threads about what to look for!!!
not trying to be rude this is just a very common question. good luck. if you dont find anything or help then ask again.

 

so i didnt find any info on how to test a coil rail on a 2000+ xj. I have checked the coils terminals resistance and by process of elimination I think that one of the readings is low... not sure if I checked it correctly or what.
