Thread: 99 GTP MAF Sensor Issues (possibly)

I wish I had a scanner so I could see what's going wrong, and where. Though I do have the ability to unplug **** until it runs right. I thought it was a vacuum leak, but now I'm being pushed away to thinking its a bad MAF. Where this goes a bit wonky, is I replaced the MAF when it started doing this & what you're seeing in the video is the replacement (2-3 weeks old now). I just now had gotten around to finding time to mess with it, and the only way I've been driving around for the past couple of weeks is just going without a MAF plugged in. When I'm going MAFless, it's a bit hesitant to rev up, might hiccup, won't be as "powerful" as normal.

Sounds like the SC is stuck open, moaning and groaning at me. I guess I should also add that when the MAF is plugged in, and I go to start it, it will start then die. Will only stay on if I rev it up, and give it some gas to 'click' into its groove.

Just tell me what you think, opinions, similar experiences. Anything and all is helpful!

*I feel like I may have to add this, but no, that's not a small cam in it. That's it idling rough.*

get the car scanned at a parts store for the code. its free at most places these days.

Last code I had thrown was a P0102 (MAF) so I had replaced the MAF (the one you see in the video). I'm honestly thinking this is a crap MAF, and will see about buying another sensor. Had checked for a vacuum leak a while back, found my boost control solenoid had a snapped nipple. Was during this same problem. Was really hoping this was where my source had been.
