The car would not idle very well about 400 rpm's. I cleaned the IAC valve and got lots of carbon out of the unit, but now it idles at 3200 down to 1500 and over and over I ran the air conditioner and it stays at 2500 or a little less. I cannot get it to go any lower. It has 12.4 volts key on and a good negative to coil. I unplugged the IAC and it did not lower the rpm's. I can remove the coil and manually operate IAC valve to desired idle. I am assuming it needs to re learn, but I tried for a hour or more with no luck.
have the same problem?
