Need Serious HELP!!!

[sick GN]

OK my car started to break up from a start and would keep breaking up as you drive. It also would do it if u revved it in park for a couple of sec. So I get started and I swap out the ignition module/coil NOTHIN. Then I switch the MAF sensor with a known good one (OFF of my bro's GN) got a little better but after driving for like 10 minutes the problem came right back. Changed the O2 sensor, computer, chip, IAC, Reset IAC and TPS. Go back out and test drive it and it runs great for 3/4 around the block, then bam the problem is back. Exactly as when I started. What else could it be????

I would check cam sensor and crank sensor. Either one could cause all kind of problems. My 02...Good luck!

How do I check those and how much do they cost if they are bad?? Also how hard are they to replace??

Is it popping at all?

Before messing with the cam sensor, I would put fresh plugs in. If that doesn't solve it, try swapping some plug wires on there.

Use AC R43TS plugs & gap em to .035.

Have they been changed lately?

The plugs and wires are only about a month old, but the plugs could be fouled from driving it like this. It seems like when it gets warm it starts to act up.

Could it be the ESC module?? Or any of the relays??

I agree, change the plus and wires first. Cheap check. A wire could be bad or a crached insulator may be the culprit. Rob them from your brother if you must.

Do you have a scan tool? Save youself time a get one and see whats going on. Seem like you don't have one because you switching sensors from another car. Did you try the paper clip at the ALDL connector.

Have you done a compression check?
