i searched but i cant seem to piece it together searching for days codes0442,p0352,p0351,p0353,p0455,p139,p0303

i was driving to work ...only a mile away.. half way there 2001 jeep Cherokee 100,000 miles fell on face didnt die ,then acted like it was on 2 cylinder ...i put in neutral and restarted, seemed to make a difference but amlost there started the same thing jeeps in good shape it was an old lady car lol kept in a garage ....hell the paint still beads water ....i checked evap lines to the best of my ability's .....thanks for the help

P0303 (M) CYLINDER #3 MISFIRE Misfire detected in cylinder #3
P0139 (M) 1/2 O2 Sensor Slow Response Oxygen sensor response slower than minimum required switching frequency.
P0351 (M) Ignition Coil # 1 Primary Circuit Peak primary circuit current not achieved with maximum dwell time.
P0352 (M) Ignition Coil # 2 Primary Circuit Peak primary circuit current not achieved with maximum dwell time.
P0353 (M) Ignition Coil # 3 Primary Circuit Peak primary circuit current not achieved with maximum dwell time.
P0442 (M) Evap Leak Monitor Medium Leak Detected A small leak has been detected in the evaporative system.
P0455 (M) Evap Leak Monitor Large Leak Detected A large leak has been detected in the evaporative system.

With that many codes in that area I'd start
looking for physical damage to wiring, either cuts, abrasions, or heat. Pop the hood and look around.

Those circuits may use the same ground too. I think its the one located on the passenger side of the engine block.

Don't worry too much about the many codes.

One single problem can trip a LOT of other sensors, because the systems are tied into each other.

I am willing to bet that your misfire is causing a symptom that's being picked up by the other sensors. Start there and work your way through the problem.

ok ive changed the coil pack the spark plugs the cam position sensor .....reset and less codes but still codes .....leak was the last code ive checked the evap in engine everything looks good but im obviously missing something

Did you check the wiring?

For the Evap codes have you checked your gas cap? 99% of the evap codes I pull are for peoples gas cap.

You may have a bad gas cap that is causing the evap leak code.

Gas cap or vent valve solenoid can cause an evap code.

The LOWEST code USUALLY trips the others. Star there! Check your gas cap THEN the O2 sensor.

any luck?
I am a 01 owner as well
I had two of the same codes, they come and go
small evap leak and contribution low
I just changed out my valve cover gasket and will be doing oil change and install new plugs
how hard is the coil pack removal and install? did you have old one tested to make sure it was bad?
My main issue right now is a battery drain-think its from a faulty dome light/switch
BTW, where is Hewitt,Tx? I'm in RR, TX

no luck i changed the crank sensor and cam sensor coil pack spark plugs ....same stalling sputtering ....if im rolling and it happens i can neutral and restart and it goes away for a while....ffffffffffffffffff

waco

Clear the codes and drive it see which return then repost results.
