Thread: Grand Prix GTP P0102

So my car is throwing the code P0102 MAF circut low input. The car will run and drive and hasn't stalled yet, some of the issues are...

-Fluctuating idle jumps around from as low as 400 to around 1600 rpm feels like its almost about to stall sometimes
-Delayed throttle response from idle
-Feels like it breaks up when I lay into it doesn't run at a steady pase

This code just came up about a week or so ago and it was intermittent, no its not it just wont go away and things are getting worse it seems. My vacuum is good its at 19 where its always been since i changed my LIM gaskets around 5000 miles ago. I tried replacing the MAF with one I had laying around and didnt help. I dont wanna go spend $120 on a new MAF and it do the same thing.

Could this have anything to do with the MAP sensor? I also tried cleaning the MAF sensor but that didnt help. I didnt wanna start a thread about this but I was doing some research on this and I see others had the same problem but they never said what they did to fix it.

Anyone else have this problem? Suggestion on what I should do?

Did you ever fix this? I see no one responded. This just happened to my GTP. I cleaned the MAF but the code came back within seconds of starting the car. Also encountering some driveability problems. Thanks.

I had P0102 last year; bad MAF.

With the engine idling, I lightly tapped the top of the MAF, and my idle would fluctuate by a few hundred RPM's.

Replaced MAF, all good.

Ran into that issue with my old GTP. Same thing. Tap the MAF a little and the idle jumps. Swapped the MAF out, all is better.
