Your Car Idle Hunting?

Your Car Idle Hunting?
i've seen about 4 threads already asking this question, so im gonna make a thread telling u how to fix this simple problem. first, it can be a bunch of things, its one of two things, the TPS (Throttle Position Sensor), or.. the idle screws located just below the throttle body.. ( not under it, but lookin from an above view, its below it, so *South*), just take a allen wrench, i believe its 10mm, and adjust the screws when the car is warmed up after about 20 minutes, let the temp rise, then start turned the wrench, and listen, 750 is stock idle.. if this doesnt fix ur problem, then its most likely the TPS, which some1 else is gonna have to help u on that, but, the idle screws helped my idle, she idles like a kitten.. and to all of u who are worried about the start-up REV at 3k, dont worry, USDM cars do that, its an auto-warmer, it helps warm the engine up faster.. that is located to the right of the idle screws.. and u can also adjust that, but i suggest u leave that be.. lol.. i hope this helps.. sorry it cant be more specific, but, thats all there is to it. =) good luck.

My idle only hunts when the car is moving and when I am in neutral. When the car stops completely, the idle is stable. I have adjusted my TPS, mess with bleed screw, adjust PFC, but still hunts from about 1K to 1.5K. Any suggestion would be appreciated.

I have the same problem as you man.
If the car is at a stop for a while, the idle will smooth itself out. If im in gear, and i put it in neutral, sometimes it goes to normal rpm, sometimes it will go to like 1300rpm, then down. If im at neutral and i rev it, same thing. Its like it cant remember exactly where to idle at sometimes.
If i just start the car up and warm it up without touching anything, then everything is normal. Only when i start hitting the throttle is when it cant remember its position.
I changed IAC, TPS, added ground wires, changed spark plugs and nothing. I have no PFC, i guess its just like that. O well.
