So i'm having some issues with my idle, most of the times when i start up my car it is sitting around 2000 rpm instead of the normal 800-1000, sometimes it idles fine but not very often. I unplugged the IAC and nothing happened, unplugged the TPS and nothing happened. I have a LT1 all the norms, 30 lb injectors, stock TB, 10.8 mm wires, mids, borla exhaust, all smog pulled off and cat gutted, a/c and power steering delete, etc. It never used to do this, but i dropped the LT1 into a RS body, i changed out the computer and everything so i dont see that being any problem. Any input would be appreciated. Thanks.

 

Is it throwing any codes?

 

No not throwing any codes. Nice pic

 

Have you checked the vaccum?
