Idle problem, RPMs keep increasing! - '00 GT
I have a 2000 GT, 168k, 5sp. Just the other day I was coming to a stop in my driveway after work and I noticed my RPMs weren't coming down to normal idle. They were around 1300rpm. I tried revving to see what would happen and they just kept increasing and wouldn't come back down! I had to just shut off the car and I'm afraid if I shut it off when it's revving to high I might damage the internals. This happened again tonight so I'm looking to have this fixed right away.
I was thinking maybe a bad TPS? IAC is fairly new, less than a year old. I haven't cleaned MAF in a while, I'll try that too. Any other possible culprits?
