P0303 again!
Good morning everyone. This is my first post so please be patient.
I have 2 2000 jeep cherokee's, they have been wonderful cars so far. The other day a code popped up. P0303. It is a 4.0. No stumble on start up. New plugs, air filter etc. This does not appear to be a hot soak problem, as this code only sets on cold start. I have never detected a misfire. Compression in # 3 is 120 lbs, just like all the rest. I have checked the wiring and can find nothing wrong. Any ideas ?
