High engine idle on a h22 TURBO
so here's the dilly-o....i just started my lude after 9 months of letting it sit, while i built up the turbo kit and some other goodies (bc, TT, p28 w/ hondata s100) and everything is good, except the engine idles at 2500rpms. my friend and i checked the throttle cable and tb, but that doesnt seem to be the problem. the car isnt tuned yet, the dyno shop just burned me a chip, so that i can drive down to there to get it tuned. ( i will be getting it tuned very soon) why is my idle so high...? any ideas?

Re: High engine idle on a h22 TURBO (killa_lude)
The thing is... if it's an iac problem then the engine "surges" between 800 and 2K-4K RPM, it's not constant. A constant high rpm w/ no codes being popped is typically a vacuum leak. It's probably the base map then ...

check again. cracks in hoses, forgot one ont the back of the itm, and check both ends of the hoses.
did you take the tb or the itm apart?

I just finished building my turbo motor also and had the same thing happen to me running a stand-alone. I thought it was the computer, but after it ran a while (about a hour running time in all) it idled down and has been fine ever since. I think mine was caused by the large air pockets in the coolant system caused by having the motor completely torn down. An empty IAC will do wierd stuff. This is completely my opinion and may not be correct...
Anyway, my problem fixed itself, hopefully yours will do the same

i just started it up, and the idle was only at 1100rpms, damn im so happy, thats so much better than 2900rpms. yeah i thought it was the hondata base map too at first.
btw this might sound like a stupid question, but where is the IAC?

no i didnt take anything apart...i did have to calibrate the tb a bit, i.e. for the max throttle, and for when the throttle is zero.

It is on the front of the Top half of the intake manifold... It has two coolant lines running into the bottom of it, and the wiring for the plug comes off the injector wiring harness.

Your coolant lines should run from the thermostat housing to the throttle body, from the throttle body to the IAC valve, and then from the IAC valve back to the thermostat housing. Did you find the plug on the injector harness? It should be a male plug with two conductors.
