ericem Posted October 30, 2007 Share Posted October 30, 2007 Hello. Trying to find this IAC valve. I saw many pictures but I don't know exactly what I am looking at. Anyone have a clear picture of the engine bay with a picture? Reason why I ask is I am noticing low idle sometimes. Thanks. BTW I ordered the seal for the IAC and can I use throttle body cleaner to clean it? or do I need use seafoam? Quote Link to comment Share on other sites More sharing options...
xrturbo Posted October 30, 2007 Share Posted October 30, 2007 Just follow the big hose (about 3/4" onside diameter) that runs from the middle of your intake tube, it runs right to it. It attaches with 3-4 10mm bolts and is normally grey or tan in color. Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted October 30, 2007 Share Posted October 30, 2007 Hi. Here's the location from my '94 2.2L. If you follow that hose you'll see the IACV/ISV there (well not in this pic of course because the plastic engine decoration is in place). Here's how I clean mine; seems to work pretty well without even removing the IACV/ISV: 1. remove IACV intake hose from air intake snorkus 2. run engine at idle (may make system a little upset as idle airflow is not passing through MAF at this point; I haven't had any problems though). 3. give a dozen or two short blasts of throttle body cleaner into the iacv intake hose. Engine will die out if you give too much of a blast. Quote Link to comment Share on other sites More sharing options...

ericem Posted October 31, 2007 Author Share Posted October 31, 2007 Thanks alot porcupine73! I had to fill up the hose with throttle body cleaner(said for IAC valves as well) and plugged it back in then just started the car and held the gas down wouldn't work if I unplugged it. But WOW after the 2nd shot in the tube it made a worlds difference no more low idle if I tap the gas. ALWAYS went to 500 rpm's after the 2nd shot of throttle body cleaner before if i tapped the gas really quick in park the engine would almost die. Car is like WAY more responsive and smooth as well, this seems to have made a worlds difference! Thank you very much!! Quote Link to comment Share on other sites More sharing options...
montana105 Posted October 31, 2007 Share Posted October 31, 2007 God-that rust just gets every where doesn't it,is this due to road salting? Sorry to interject on this thread!!! Quote Link to comment Share on other sites More sharing options...
ericem Posted November 1, 2007 Author Share Posted November 1, 2007 Must be with my car I don't have any though. I think its because my dad always got a car wash in the winter and would rinse out the engine bay. Quote Link to comment Share on other sites More sharing options...
jcniest5 Posted November 1, 2007 Share Posted November 1, 2007 God-that rust just gets every where doesn't it,is this due to road salting? Sorry to interject on this thread!!! A good engine degrease/wash every once awhile wouldn't be too bad of an idea. My 91's engine looks a lot cleaner because I clean it regularly. Me, too, sorry that I have to offend someone here...forgive me. Quote Link to comment Share on other sites More sharing options...
