Initial high idle?

Post by forcefed86 »

This is on a 2006 GM LS 4.8 with IAC control.

What parameter controls the initial idle right after initial start? When I first start my car (hot or cold) Idle jumps up to 1500 or so and hangs there for 30 seconds or so. Then it settles to 850 or so and idles great. IAC controls and all work great after that.
