The remaining likely inlet of air is confined to the Bypass Air Control Solenoid Valve and the Auxiliary Air Control Valve. The BPACSV comprises a rotary solenoid, held in the normal idling position by means of a permanent magnet, which provides only limited torque. The associated rotary valve could very easily become prone to sticking in an open position, i.e. in the controlled position, normally used to counter temporary parasitic loads. Although access is not easy, dismantling, cleaning and checking the mechanism is a simple procedure. P.S. The air inlet to the BPACSV consists of a quite large flexible tube, which runs across under the throttle body, to a junction under the main air inlet duct. If you disconnect this tube at the duct, you should be able to get it into a position whereby you can inject some solvent down it, so that this reaches the rotary valve. CRC petrol or whatever may dissolve gunk. If you switch on the ignition, then the air conditioning on and off a few times, this should operate the valve. The AACV is more robust, mechanical temperature reactive and I would rate as the second most likely culprit.

Note the P.S. I have added regarding a possible method of cleaning the valve.

Well... my car is been idling from 2200 to 1800 consantly.... since I cleaned the IAC, maybe i did something wrong, i cleaned it with carburator cleaner... then took the electromagnet out and lubed the inside with WD40... I wonder if the WD40 could affect the electromagnet..... Also..... before cleaning it my idle went from 1600 to 500 in a very slow motion... wich makes me believe the valve was partially clogged but working, and now its not working or is on open position all the time.
I noticed it has an adjustment similar to the TPS sensor.... but I left it in the exactly same position it was before taking it appart.... is there a way to test it?? If I turn on the AC the valve should move and change the idle??? Thanks. |

I had this ame problem with mine, it was clogged and I cleaned it up. Apparently it had been clogged for a while, because it had been adjusted to compensate for the gunk coated throttle body. I think the main difference was actually cleaning the throttle body butterfly valves, they were completely closed because of the gunk before, but now they have a small gap all the way around them. To compensate, I adjusted the IAC farther closed. I left the valve approximately 1/3 the way open when unplugged and in place in the throttlebody. Try it, I bet it works for you!
BTW, if it's a little off at first, it will adjust over a few days and be back to normal in no time!

Later in the day, I will do a write up on cleaning, testing and adjusting the BPACSV (IAC) valve.

Make sure your intake hoses are fastened to the throttle bodies all the way. Last time I took mine off, I put it back on with part of one of the two rubber circle tube thingies bent inward, letting in air. It would idle high sometimes, other times idle normally..
