Have Ford Ranger 2004 3.0 with manual trans. Get run away idle at weird times. Will start truck and drive it go to clutch it and idle will be up to 3000 rpm. Replaced IAC and ran fine for about 3 days and problem came back. Disconnected wiring harness at PCM noticed a little moisture inside,cleaned pins and connector with electrical contact cleaner. Once every thing looked dry reconnected and every thing was ok for couple of days. this problem is not every day it is very random, but worse if using A/C. Have used scanner and am not getting any codes.
