Idle dips stalls sometimes in park.
Went to start my car this morning and put it in reverse and the rpm's dipped almost to the point of stall. Then it jumps back to normal. So I leave it sitting idling and every 2 min or so it would dip and level off at 700rpm. I pulled the maf and cleaned it pulled the other top tb sensor not sure what its called, and that one was a bit dirty. So I cleaned that one too. Restarted and it stays on and doesn't stall but if i put it into gear it will bog down and want to stall.
Any ideas, I did a search and that was how I knew to clean the sensors but that didnt seem to work. 2000 GTP 140,000

Re: Idle dips stalls sometimes in park.
Sometimes when i put it in drive it seems ok, then i drive 2 seconds down the road and it kindo of acts like its low on gas and dies. But i just put gas in it so I know its not that. But im stumped, guess it could be the 02 but not sure. I cleaned all the tb sensors and checked for vac leaks. Nada
But when i leave it in park it idles ok for a bit then just bogs and revs to catch itsself then eventual dies. But i will start it right up and it seems fine for a bit, then repeat the same shit. Giving it more gas it doesnt choke or anything, seems to rev fine. Last edited by MassGTP; 04-23-2011 at 12:00 PM. Reason: more info

Re: Idle dips stalls sometimes in park.
Try disconnecting the harness to the MAF and start the engine with it disconnected it might stall the first time, just start the engine again and see if the problem goes away.

Re: Idle dips stalls sometimes in park.
Ok, I unplugged it and it seem to run ok but same issue. After 2 min of idle it drops and revs to catch its self and eventually dies. But it didnt drop as much as with the sensor plugged in.

Re: Idle dips stalls sometimes in park.
I tried the fuel pump resister trick bending pin 85 to put it in high speed mode and it seemed to work. Hasnt stalled or bogged yet. So what does that mean is going? the fuel pump?

Re: Idle dips stalls sometimes in park.
I'm not sure what's the problem with it (I own a GT), only thing I know it's related to the fuel pump resistor. There is a rewiring kit available at some autopart stores.

Re: Idle dips stalls sometimes in park.
