ENG: Cleaning out IAC Valve

[JTEK24]

it could, try it out, couldnt hurt. also check for vacuum leaks. have u done any other mods to it that would cause it

Well i cut the hose that runs from the stock intake system i think its the number 8 hose, and stuck a screw in the shortened hose thats on the throttle body. I did that since i put a cold air intake in and wasn't using the hose anyway. Im not sure if that had anything to do with it but I will try cleaning out the IAC valve this weekend.

Will this solve the idle problem for the constant up and down rev problem?

I just swaped in a H22 into my car and i have the up and down rev problem...i took this part off several times cleaned and put back on..helped a little but it is still rev ing up and down every once on a while

[sd93accordEX]

mine will do the same but only if i bump the gas pedal while it is warming up. if i leave it alone, it idles right where it needs to be after it warms up. once it is warmed up, no issues whatsoever.

I did this a few days ago. I just undid the 2 bolts, and unplugged the harness and tipped it upward and used a tooth brush and some wd40 to clean it good...all I had...worked good, but dont notice anything diff...but good to know its cleaned out...

is it ok to use WD40?

[PiercedLip81]

i just sprayed some on the toothbrush and scrubbed it. I didnt saturate it, but i figure wd40 is a good do it all type product, so what the heck. No probs for me...

question about idle:

you said if it idles weird or whatever,adjust it by the screw? what screw? any pics of it and how to know if im adjusting it correctly. i never messed with the throttle or idle adjustments at all.

Look at the top of your throttle body and then look to the left of the red hose (it's red on mine), there should be a flat head adjustment screw. That is it. BTW great DIY I'm going to do this tonight while my H22 is in pieces. :tu

i had to remove my strut bar to get to the lower one, that screw was a bitch

[93accordexcoupe]
