Well the engine idles about 1100-1200 rpm once warm. And 1300-ish when cold. When coasting it stays about 2k.
I've got the IAC adjusted as far out as it can possibly go and still fit in the casing. All I can do with it is tighten it up more, which raises the idle.
I've got the throttle plate adjusted about one thread away from sticking. I could probably close it another half turn, but I just don't see that idling me down to 800.
Tps is new. All vacuum systems have been deleted, so there's no leaks. Vacuum gauge reads about 13 once warm at idle. Is that low? It seems low compared to other engines I've seen.
Is it possible that my IAC is bad? I've got another one I can try to see if it works alright, just haven't gotten around to doing so.
I can't really think of any other reasons why it would be idling high. With no leaks and everything adjusted right, it should idle at the stock number, right?
