Idle\Throttle problems

[Hethj7]

My car likes to idle near 2,000 rpm and even when driving it tries to pull itself up to that speed even if I am wanting to be below that. It doesn't always do this but it does seem like it may be more consitent (as far as staying at 2,000) at hotter temperatures.

I set my TPS, cleaned the IAB, replaced the computer (which I though was the problem), and checked my ECT. I may go double check the ECT since the problem may be somewhat temperature related. I can apply current to my IAB and it moves back and forth fine, but is it possible that even though it moves, it is out of range and needs to be replaced?

What other things can I look at? This one has got me stumped.

What other mods do you have? Different MAF, injectors fuel pump/regulator...?

Sorry it is taking me a while to get back to this....my internet was down the last couple days.

I have all the usual bolt ons....70 mm TB, 70 mm MAF, 190 lph fuel pump, still running 19 lb injectors, GT-40 heads and intake, B-cam, 1.72 rr, pulleys, headers, etc.

It has quit having problems all of the time, but even when it idles "down", it stays at about 1200 rpm's or so. I have the idle screw backed completely off and removed my idle air plate years ago (went between the IAB and TB to help in correcting idle probkems).

I am up for any and all ideas at this point. It does seem like it has a greater problem in hot weather, although it is not real consistent. I am just having real troubles pin pointing this one.
