so ive been searching this for a long while now and just cant seem to figure out what is causing this. i would rather not take it to the dealer and most people online say the dealer doesnt really help much either.
so i have a 06 liberty 6spd 4x4. check engine light came on for random misfire blah blah blah. so what i cant seem to understand is what other parts can i look for and test, if possible, that can be causing this? p0142 (o2 bank 1 sensor 1) just came up yesterday, but i get no other codes for single cylinders. i dont see how it could be coils, injectors, or plugs because if this were the case it would throw the cylinder too i would think. ive changed plugs, crank sensor, and fuel pressure was at 60lbs for about 10 mins straight, also swapped the asd relay with blower relay and it didnt help. i know there is a ton of other threads on this, but im not sure what else past what ive done can be checked or looked at by myself.
thanks a ton guys.
