Having problems with your 2002 Jeep Liberty ?
2002 jeep liberty limited 3.7 L. scanner shows bad coils......A,B,E primary/secondary which I dont understand because they are a solid unit.....replaced 5 of them...all i could get....and oem plugs. cleared codes....still have same problem and same codes....I have dealer manual and i am level 2 chrysler mechanic.....I no longer work for chrysler but know a lot about all vehicles...I cant check compression.....any other ideas..what about IAC solenoid ?...I am clueless...or should I find comp.test
Unusual to have all the coils bad at once, I would look at the common denomenator such as a bad ground or power source.
