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.*

 


go on ebay, buy a 20$ used acdelco one and throw it in, its two screws holding it in.

same thing happened with my 01 gp gt, it would start die right away, unplug maf sensor and it drove just fine. put new sensor in, and never got the code again and its been driving great.
 
spray the vac lines with carb cleaner, if the idle jumps up, you found a leak.

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.
 
If you bought that replacement MAF at autozone or something, yeah i'd suspect it to be trash. Get a delco one, then try and get a free replacement on your current one, and sell it on ebay or something to recoup some costs. Also, snapped nipple *shudder*
