Comments about CARQUEST by BWD Idle Air Control Valve:

I'm not quite sure this was the part I needed to replace, I replaced it at the same time I replaced the throttle position sensor. To replace it you only have to bolts and just pop the electric connector. In the end my idling problem was corrected for under $100 so it beat trying to take it to the shop.

    Exact fit. Took about a day for PCM to re-learn idle speed. Then all good.

        Comments about CARQUEST by BWD Idle Air Control Valve:

        1989 F250 was running very rough - especially at idle. After much research, I found that replacing the Idle Air Control (IAC) Valve and the Throttle Position Monitor (TPS) takes care of the problem a majority of the time. So I got one of each from Advance, spent 2 hours installing them (they're both on the throttle body, so you do them at the same time). A professional technician could swap them out in under an hour, but I'm not a pro. Anyway--replacing both items did the trick!

          I bought the IAC after considerable research about the high idle on my truck. The idle is now higher than before. Don't know if this part was faulty. Should I try another?

            The old style had an adjusment knob so you could set the idle yorself.

            • Q:

              I have a 93 f150 that will not idle. I checked the IAC valve according to the haynes manual. and the ohms check is good, at 9.7. but the voltage check is reading 12.5 volts. The manual calls for around 10.5 volts. Is this a problem? The valve and throttlebody are free of any carbon deposits. Is there any other reason it won!t idle? other than the IAC valve. Runs great other than the idle problem.

                Yes, the idle air control valve should be the possible cause of the problem. However, I would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem.

                A:

                The basic signs of a Bad Idle Air Control Valve are Low RPMs, Stalling, Rough Idle, Weather Variations. If the temperature outside is warm enough, the car may start even though the idle air control valve is bad but will require the driver to immediately press the acceleration pedal to keep it from stalling.

                I have a 91 Ford F-150 that wasn't idling properly so I removed it and looked inside the bypass chambers and it was full of black carbon deposits. I cleaned it with carb cleaner to remove the deposits and reinstalled it. It smoothed the idle out and I didn't have to relace the control valve. If its dirty it won't allow enough air to bypass during idle so it won't idle properly. It very simple to remove the complete valve and check for carbon. It could save you approx. $75

                If the idle does not change, then there is a good chance that the idle air control valve is not working properly.
