Occasionally my (when it still had the auto) would, upon starting it up cold, idle extremely low until you drove it for a little while (like 300rpm), I switched to a six speed and had a chip for it burned from pcmforless. The idle was way too low, so i mechanically idled it up (which made for an rough idle, due to the air distribution not being even, since it was coming through the blades instead of the iac passage). This worked for awhile, then again the idle got progressively worse. I finally broke down and bought a new iac (idle air control) valve, and I have driven for a couple hundred miles, but still it tries to idle at around 550 w/ the a/c off, and like 500 with it on. Sometimes when you first start it cold it tries to idle at like 400. Also, the idle is very surgey (i know that's not a real word) varying sometimes like 75 rpm or so (it bounces). The car still runs terrific, just not at idle. The idle is so low that it is causing the battery to discharge b/c the alt. is not spinning enough. Any help/suggestions would be greatly appreciated.

 

should i just get my chip reburned to idle like 200 rpm higher or what.... someone has to have so input!
