Stumped w/ a High Idle

[mrvanparys]

Hey everyone,
I have a 94 del sol with a d16y8 swap. A few months ago it began to idle exteremly high out of the blue. It now idles at 4k. I have tried 3 different Idle Air Control valves, I've checked all my vacuum lines, tried a different ecu, tested the TPS, and tried adjusting the idle screw. I even took it to a Honda dealership and they charged me $80 and they came up with no answers. I was wondering if anyone else has any ideas because I am stumped.
Thanks,
Mike

a friend of mine had the same prob with his b20 in a rex, except the problem ended up being his valves were bent. everytime he started it up it went straight to 4-4500rpm's.
