i dont know can you help?

well it has been happening more often now. when on my way home from work in the afternoon when it seems to be the hottest outside and i come on the highway and i gun it to get out ont ot he highway,later during my trip my car seems to have a high idle....like the cruise controle is stuck on becasue of it. and thus thoring the shift points off. i was thinking maybe something is stuck open or something with a vacum leak or something.

but like i said it dont do it all the time seems like when its hot outsdie and the car warms up thus making the car hotter. it seems to do it

i dont know, the throttle body plate isnt stuck open nore has the throttle screw been messed with to alter the idle.

when sitting in drive at a light or stop it will be at about 900-1000 rpm, and when i accelerate to about 20 mph, and let off the gas, the mph actually climbs.....

soooo can ANYONE show me toward what i should look into.

thanks for NAY advice

My first thought is your IAC valve. Other than that on my 96 my MAF sensor started going out and it was screwing with my idle. But I'd say start with the IAC. The excessive heat might be causing it to malfunction.

if you think it may be the MAF, just unplug it...

Extremely bad advice. DO NOT unplug the MAF as a way to fix the problem because you aren't fixing anything. In fact you may be making it worse. The MAF is an integral part of the powertrain control system and unplugging it will force the computer to operate in "limp home" mode. Your gas mileage will decrease, you A/F ratios will constantly be off, your power and driveability will suffer, and you will hasten the demise of the catalytic converters. If the MAF is bad (which it probably isn't if no codes have been thrown) then it needs to be replaced, not unplugged.

A vacuum leak would tend to have the same problem consistently so I would say no. But check thoroughly nonetheless.

well im not guessing the cruise control, cuz it will actually speed up with the hgh idle lol. but thanks alot guys for the quick responces. i broke the fins inside my original IAC and got one from the junkyard from a car with i think 100K on it. so maybe this one is going bad, oh well it was cheap.

like i said i gave it a good cleaning, ill see how it works tomorrow.

thanks again
