Ok, now im confused.........

Ok, car misfires under load. Got that pretty much nailed to either fuel filter or the Cat. Havent gotten around to either one yet. Still not throwing any code. Just misfiring. Now 3 times this weekend. I start the car, and it immediately dies, not only does it die, it resets my tripometer, leading me to beleive that its reseting my PCM. 3 seperate times it did it. It doesnt reset my radio stations or anything so i dont think its a battery ground problem. Im so lost on this car. Any suggestions, and like i said, no codes, so i have no clues on what the problem might be. Any suggestions are welcome.

Ion, don't know what happening but hope this helps,
A few months back I was getting a low voltage MAF code. It would set immidately even if I switched sensors. I unpluged the MAF and ran like that for a while. A few weeks ago, I got out of work and my car wouldn't start. It would rev and die. After a while I got it started but it missed real bad. Got it home and plugged in a fuel pressure gauge and it wouldn't go up to 38 psi it would stay lower and then click and would go up. Finally it would not build enough pressure at all. I thought regulator, relay or pump. But one time I tried to hook up a scanner and it didn't want to read the computer. So I got one off Ebay for $26, plugged it in and has worked fine ever since. Even no more MAF codes. By the way, whenit wouldn't start I threw no codes, just the MAF from months before.

When my car was missing, and i could feel it bad but got no codes, i actually sucked it up and beat on it for about 3 minutes, then a code came up, and i got it scanned to a coil pack.

Try that...

hey Coriya71, i got a low voltage maf code about a month ago and cleared it and it never came back. So did you replace the computer?, what did you replace to fix it. Hopefully thats it.

Yeah I pick up a new PCM on ebay. Took 5 minutes to change which was good because I couldn't drive it for 3 weeks because I thought it was a ground too. (when it would run there were times it looked like someone had cut power but right before it died, it would go back on. It was wierd. I was this close to replacing the fuel pump. But it's been about 3-4 weeks now without 1 problem.

yeah mine does that and has been doing it for a while now. Like at a stop light, the voltage will drop, the rpms will drop to like 400 then it will catch. I thought it was a fuel problem. But the PCM sounds like the real deal. Your describing exactly what is happening with my car, i got the Maf code, i got a TPS code, and nothing since, with crazy misfires under load. Then i started it this morning for work and came back out like 3 minutes later and it was dead, took a while to start it. Looks like ill be getting a PCM. Thanks man.
