[RESOLVED] Weird stuttering problem need help ASAP

[srtkiller]

I getting a real bad stutter at idle and under any throttle condition and my wideband reads pig rich under throttle and is very erratic at idle. My tps percentage jumps around from .3 to about 2.4 at idle. I did a boost leak test last night and had a couple little leaks I fixed those and it got a little better but not much. Is it possible for it to be a tps or maf sensor causing this problem. Ant input will be very helpful. And yes my bov is recirculated.

A bad MAF is possible and is a likely suspect if there are no air leaks. The TPS sounds okay my brother's 2g has a couple percent reading at idle also.

Try unplugging the MAF and seeing if it makes any difference. If it makes any difference, your MAF is fine. If nothing changes, then your MAF is bad and you need a new one.

I would also check all of your vaccum lines, change the spark plugs and at least test your wires.

The problem is solved. I was driving it home last night and it was still running like crap, I parked it at the store and when I came out it ran perfect. Then I drove to the parts store to go pick up an oil filter and it started studdering a little on the way home. When I got back I seafoamed the car and in the process of fogging the neighborhood it started to run perfect the idle smoothed out and started to pull like never before. I think what happened was the computer was trying to compensate for the boost leak that it had. Now there is no boost leak and the computer re-adjusted itself. Either way I don't care it runs better than it has in while.
