Hey guys I have a 92 Camaro Rs I just totally restored, engine is a fresh rebuild with everything going in new. I just have a question, I got everything running, it is timed at about 6 degrees and have everything plugged in. (all vacuum hoses no leaks,). The problem is when i'm coming to a stop, the engine remains at a high idle, about 1250 rpm, to almost 1500. I dont think it is the normal throttle body sticking, because it doesnt happen when the car is parked, but I am wondering what might it be.

Any information or tricks would help.

Thanks

I have the same problem with my car. I feel like it onl does it when it's warming up. I have not rebuilt my engine or anything and have 130k.

Mine is when it is warming up and when I come down to idling. I also have some pretty high oil pressure according to the gauge, around 45 psi?

Would any lights come up on the dash?

Did you make sure the EST was unplugged when you set your timing. 6° base is a little too much for these cars. It isn't required with the swirl ports and can cost you driveability. I would check the timing, set it to base 0 and go from there. Might be a good time to check TPS voltage as well.

I am not getting any codes or anything, just a weird bit on the idling coming down and a fluxuation on start up, Nothing horribly bad but it is annoying on a new engine.. I am going to check these things out here in a bit, I am at work today and will check it when I get off.

Have you found a solution to this issue? I'm having the same problem still. Maybe it's my IAC??
