All right, this shit just started yesterday and its pissing me off. Whenever i start my car, the rpms go straight to 2000....then it drops to 1k then back to 2k and keeps going back and forth..............my friend said it was a sensor, and ran about $60.........is he right?.......thanks

 

....help......

 

Fast Idle Thermo Valve, it can be fixed without having to buy a new sensor.

 

LOL....damn fucking irradic idles....I know how you feel man...been dealing with it for like a month now....Im told something different every place I take my car to.

 

mines the opposite. It idles fine when cold. but if i drive it (cold) , the second I take my foot off the gas she stalls... when warm its perfect though, idle and driving.

 

mine does the same shit til i put it in gear then its fine ??????

 

lol, i think i have you all beat, on a 91 dx , d16 a6 motor, starts fine cold, new plugs, new plug wires, new fuel filter....when im driving if i even take my foot off of the gas pedal it stalls, the idle is fine on it, and when i drive it jerks if i mash the pedal past a certain point, been like that for about 4 months, i have no idea what it is doing, thats why im just doin a swap

 

What do i need to do?.....i sit in the high school parking lot just idleing, and everyone thinks im doing it on purpose to be cool or something.......

 

what else might this be called ? I dont think thats my problem though.. you just have to see my car to believe it. I might tear it apart this weekend... she runs rich as hell to.. I hate that. And ever since I put the valves back to OEM stettings it seems to have lost power . they were open as hell and I closed em up to factory specs.

 

i think it's also called the IAC valve...Idle Air Control. It should be on your throttle body...a big plug looking thing....which I guess all sensors look like
