Sure, I have checked all of these on mine and still have not found it yet. But this is what I have gotten from everyone. 1, Fuel Filter, 2. Fuel pump, 3. TPS, 4. MAF. Not sure but I am going to check my plugs tommorrow and see about them. Good luck

yeah but there are so many things thatcould cause a miss. mine ismissing because of a bad valve. so jojo2003 ide do a comp check on all ur cylinders right after it misses, so if ur like me and have a bad valve ull catch it then. but when he switeched to the aftermarket msd cops he might not have a good connection on one or more of the coils.

u check compresion then poor a lil tranny fluid in the cylinder, turn it over for a sec then check the compression again. if it increases then its a valve. if it doesnt its a ring. also if it was a ring ide be loosing oil. and im not. its a valve.
