Im getting a miss it only happens sometimes. I can drive for an hour and it will be fine, then park and drive again and it does it. I have changed my fuel filter, checked my wires new plugs, cap, rotor, cleaned my MAF and checked my TPS,i have also checked for vacum leaks. and 2 new O2s.timmings at 10 dig, lots of fuel injector cleaner. i had 3 codes on the computer 31 41 91, after i changed the o2s i cleared the codes and its bin a week and they havent come back. it never happins when the car is cold and and WOT. If i sit in neutral and rev it passed 4 grand it will miss too. please give me some help the car runs perfect besides this stupid miss. my fuel pressure is at 41 at idle, it misses at idle 2 somtimes. thanks alot

you said you "checked" your wires. have you actually replaced them?

they could still be arcing...

 

Do you have an aftermarket ignition box or coil? These help the most when the engine is hot and at high RPM.

 

hmmm, i'd definately check the entire ignition system and make sure every part of it is working properly!!!

 

hey i am having the same problem someone told me that it could be the head gasket but i having taken the time to look yet what do you think?
