So where are you trying to get your idle 100 or 1300 ??

If you hit 1000 and need to go lower- adjust the dizzy to compensate for the extra rpms your getting.

i did an compression test pistn 1 150psi piston 2 155 piston 3 155 piston 160

That sounds good (for a 20-year-old car) as stock compression, IIRC, is 173

um... are you sure you're throttle cable isn't too tight?

The IAC valve is a culprit of this problem. My 3SFE does the same thing. I have found that by blipping the throttle she will idle back down to ~1k, normally she is idling around 1.3k.

You can take the IAC off and use compressed air to clean it out, sometimes this works, or you can buy a new one. Since they run a pretty penny, most folks use the compressed air method.

Myself I have been driving the car for over a year with the funky idle.
