Check your IAC motor (idle air control) located on the throttlebody. It seems like there was also a TSB on the TPS.

my car is doing the same thing, but when i put it in neutral it is reving up to 2000 rpms and it idles in park at about 1400-1600 rpms so if you got it fixed could you please tell me what was wrong with it. Thanks

hey tofast after you locate it then what. How do you know if it's working or not... I'm having the same problem pretty much.

My Malibu had the same thing wrong with it except it would do it all the time no matter what gear it was in. It would usually start once the car warmed up. I purchased the IAC motor but the stealership wanted to $90 just to put it in because they said "they would have to hook up the diag computer after it was installed" which is a bunch of crap. In my repair manual for the Malibu, it said in order for the computer to recognize the IAC motor after it's installed, all you have to do is turn the key to the 'ON' position three times and on the third time, start it. I couldn't replace it myself because there are two funky-ass screws holding the IAC motor on, and I couldn't tell what tool it was exactly that I needed. Becareful too because those funky screws strip REALLY REALLY easy.
