Engine wont' idle under 2,000 rpm
 

When I first start my car up, it idles fine. But, after driving for a bit, it idles around 2,000 rpm and does not kick back down to normal. Nothing mechanical seems to be wrong, such as my cable being in a bind or the butterfly valve being stuck open. Could something be wrong with my IAB? Give me your thoughts.

i thought hanging idle means tps.... but i am not sure

That could be, but I don't know why it would have changed all of a sudden. I should get some time throughout the week to look at it. If I can get a hold of a voltmeter, I will check TPS to make sure it hasn't changed.

I dont know what your problem is.. but sensors are wierd like that.. they just GO... I had an 87 chevy celebrity and one day it wouldnt start.. turned out it was the CRANK POSITIONS SENSOR... it ran fine when I parked it... the next day.. nothing... a 12 dollar part cost like 100 bucks to replace.. kinda funny like that.. so if it's your TPS at least its easy to replace

Pull some codes.
 

Have you tried to pull any codes?

I haven't pulled any codes yet. I should have a chance to do that today or tomorrow afternoon. I will let you guys know what I find out when I do. Thanks for the replies!

I think my money is on tps. But then again it could be somthing else but it is weird how sensors just go like that. It can be so agravating
