P0301 jeep liberty

Question

I pulled the codes for my son's 2003 jeep liberty 3.7 liter engine p0300, p0301, p0302, p0305, p0306. What should I start looking for?

Answer 1

Misfire codes, clear the code condition and start the engine  allow to idle , the engine should set a CK ENG LT, either it would be pending  or become a store code, what ever cylinder comes up as a misire check that ignition coil. The first thing to start and to suspect would be the ignition system which is very prone to be the cause.
