Thunderbird idle problem
 
It's not fbody related so I put it here in the lounge...

Got in the car to go to class and as soon as i started it the rpm's shot up to 2000 and sat there for a while then came back down after waiting for a few..eh. So I get to school and as soon as I took it out of D the rpm's shot up to 2 grand again, waited a while..still stayed there and I had to shut it off. Came out of class 2 hours later, same thing only this time the rpm's wouldn't drop, though they'd dropped to 1500 and then something made it jump back to 2000 again. Along the ride home I could feel I was braking against the engine and same thing when I put it in park. Any ideas?

specs:
94 thunderbird, 3.8 V6 51,xxx original miles

IAC valve?

I think I found it, It's not hard to replace so I'll try and save some cash and just use carb cleaner and see what happens lol

Yeah, a cleaning might fix it. Do you have a Thunderbird S/C or a regular 3.8 Thunderbird?

regular 3.8

get throttle body cleaner and hit all the IAC and related passages.

cleaned the IAC..fail, so I forked over the $82 and got one from autobone with a 2 year warranty..car runs beautiful.
