Chaned IAC, now extremely high idle. Hey guys, I have a 1998 Trans Am and I changed the IAC in it and now its idling at about 2500 rpm. Is there an adjustment screw on the LS1? or is there a reset procedure I need to do?

Never mind again, it was fine this morning when I got up, the idle was a bit higher than normal...but I didn't think anything of it. Now I went to lunch out today and when I turned it on, it idled up to about 2200 again, but it slowly started to go down. As soon as I put it into reverse it came right down to normal. What causes this?
