Idle Problems With D16A

[Olskool Integra Boy]

Hey, my 86 integra is having some problems in that the idle tends to fluxuate while driving, often it gets as low as 5 or 6 hundred revs and obviously stalls, then, on one of these occasions it would not start again, i guess beaues the idle was still too low to kick it over. the idle adjustment also seems to be faulty because it can be adjusted down but it wont adjust up beyond about 1100 revs. this would be fine if the engine stayed their for the whole journey but....
has anyone herd of this happening before or have any ideas how to fix it.
any help would be geat thanx.

common problem with Hondas, its usually the EACV valve, do a search for mo info,
there is a DIY clean EACV thread in the Articles/Reviews forum

Yeah, I had these problems as well, mostly when the car was restarted after a short stop. It still happens occasionally in hot weather where the idle rises, the car overheats and won't restart.

But as ECU-MAN said, it's the EACV/IACV on the back of the intake manifold, i'll try and get a picture uploaded

It was quite easy to remove, but I had the throttle body completely off and removed all the tubes. IIRC there are 2 coolant hoses and 3 10mm (or 12mm?) bolts. If this does not solve the problem then maybe look at the radiator+overflow level as i did this at the same time.

olskool,...you might want to check the idle adjustment screw path is clear in the throttle body - they have a tendancy to gum up and not much air will be able to by pass. Sounds like this might be happening when you say you can't get idle above 1100 rpm. Other thing to check is the igniter module on the distributor - this gives some problems with restarting when hot.. :honda:

also check your throttle cable is set correctly. I had this same troubles aftre cleaning my IACV. Just a quick look in the user manual had me checking the throttle cable to discover it has never been adjusted properly!!
