When I first got my protege it wouldidle really high(after reaching operating temp) about 1200,1250. the 1st thing I did was adlust the idle screw so idle would drop to 750. It worked until I was braking for a stop sign/red light or clutch in with 1st engaged rpm would drop really low(500 or so). I ended up findin the aic as the culprit and replaced it with a used one from ebay for 20 bucks- a very good deal I may add as this item is.. shall we say, pricey. That fixed the **** out of it. my concern now is that rpms still drop to about 600 650 while cluch engaged and in first, which I think may be a left over side effect from when I adjusted the screw to compensate for high idle. What I want to know is the PROPER way to adjust idle with this screw. Ive searched the archives and got a few different procedures on this. Any help/ input would be great. Thanks.

your supposed to reset the ECU for it to take effect.
I did mine w/o reseting the ECU and I have not had any problems. -
I had the battery disconected when i put on aic and before i replaced it when i set idle down to 750 i disconected battery and let set for an houe or so. I always do that when i move the screwOriginally posted by D323Comment

did you jump ten and GND in the Diagnostics box?
Oh and you dont have to wait as long if you disconnect the battery and mash the brake pedal..Comment

Thats what I was wondering. I read that about the diagnostic box, but i was also getting some oter info as well. so i shold jump ten to grnd, then adjsut rpms accordingly.Originally posted by D323Comment

I knew you had to do that to adjust timing, but not adjust idleOriginally posted by 92dxComment

Erm I just adjust the screw and it works...my current problem is that my idle stays high for a while then drops down...not like cold start, this happens after driving when at idle at a stop...

but it only does it when you're holding the clutch down to the floor, waiting to let it back out, right?

The reason for it to stay idling high is the dashpot. There is a little screw that points up and presses against a diaphram. Turn that bolt loose a turn or two and lock the jam nut. Tha should help you. You don't need to reset the ecu in order to adjust idle. That just doesn't make any damn sense. Its a manual adjustment not electronical.Too bad I have AWD and you don't!

How could you adjust it then reset the ECU...if it "compensates" as you say, you'd adjust it to the right idle, reset the ECU and it would idle different. You'd never get it right. And it's mechanical as said.
