Ok guys, this has been happening to my car lately, and i have no idea why.

When driving, i have noticed there are times when i would come to a stop, and when i take it out of gear, the rpm stays at about 2000-2300rpm for about 5 seconds then it drops back to normal. it does it for at least 4-6 more times then it stops.
it happens about twice a day. does anyone know whats wrong?

 

i dont know if this helps any but i notice my car only increasing the idle rpm to 2000 when i first turn the car on and start driving around and +200 when im running hvac. are you using air?

 

what do you mean by using air?

 

a/c? perhaps?
wintertime....dont think so lol

 

dang it, i have no idea what it is, kinda sucks! when changing gears, i feel like im glazing a tad bit because the rpm stays high.

 

difficult to imagine what this could be.
try operating the throttle butterfly from under the hood, does it move freely without catching on anything? visually inspect the throttle cable.
check inside to see the carpet is not obstructing the accelerator pedal.
clean the IAC it could be sticking open.

 

do u have an intake? check ur intake hoses... see if you see any holes in them or if one needs to be replaced

 

no holes on the intake tubing and i just recently cleaned out my throtle body. man, i dont know what else to check.
anyone else?

 

check your IACV might be dirty.

 

hey man that could be your throttle postion sensor, is your check engine light on
