My car just started running like junk today. I JUST replaced the ignition module for the 3rd time in 7 months and that did not fix it. It seems to run sparatic like ther is no fuel or spark and then revs with out me touching the gas pedal. I ordered a 300 super coil since i still have the oe one on the car. I guess it might be the mass air flow. My ses light comes on and off. I have a fuel presure gauge in my car and it stays the same even when the car shuts its self off so i don't think it is a fuel problem. Would the coil make the car do this? I replaced the TPS about 3 months ago so that shouldn't be it either. I know i will never buy a napa sensor again. Any suggestions would be great. I also put the stock chip back in changed nothing. If all else fails My brother will run it off his computer tommorow.

I would get the codes before you replace any more parts. If you post them here, someone will let you know what they mean, then you can replace parts.

Have you checked the magnetic pickup coil yet? I had a problem where excessive vibrations(normal road vibration) caused my worn pickup unit to cut out.

Its been about 4 hours and i went out and started up the iroc and presto it fixed itself. I drove it about 5 miles and even tested my nitto drag radials WOW!!!! I'am afraid in a few days it will act up again maybe. Do you think the computer just needed some time to get used to the ignition module i put in this morning? Could it be the MAF is just temporely working? Any case the nitto are a must for any one running 14.5 too even 11s IMHO
