I have a 1981 Camaro Z28 and its been running perfect so far this summer, today i started it up and it usually sits at 1500 rpms until it warms up and then it drops to 1000. But it started up at 2000 and so i let it sit and idle and warm up but it never went down. I put it in drive and it went back down to 1000 (normal), but then when i put it back into park it jumped right back up to 2000 rpms again. I took it out and it ran fine, it was quick on the throttle and when i took my foot off the gas it would speed up to 30 km and it would do that without my foot on the gas until i pressed the brake. WTF Is Wrong!!!!

 

first try dropping your idle control. warmed up it should idle around 800rpm.
