My wife's 2k GT has just over 60k miles on it and in the past month this issue occurred twice on different days. The 1st time she came to stop and all of a sudden the rpm climbed up to 1500 and she cruised home without touching the gas pedal. After it cooled off it never did it again till a couple of days ago. She said the next stop she put it in neutral and it settled down to normal idle in a short time and stayed that way all the way home. Coincidentally, I also have a 99 Olds Silhoette minivan with the same motor and tranny and the high idle issue happened once. Again, after cooling off it was OK. So what do you fellows think. BTW, no codes on either vehicle. Thanks.

Am I the only one with this problem? Any guesses? Thanks.
