OK. Was back to looking for a vacumn leak using the Haynes-suggested method of using a length of tubing as a stethoscope. Heard a faint hiss at the IAC, around the little nubby bit that points to the rear of the car. Then I blipped the throttle pretty hard and the damn thing moosed like crazy. Did that everytime rpms got high enough to open the secondaries. It even died once after the moose.
Could a leaking IAC valve be causing these codes? I assume that cleaning it won't fix a leak so it must be replaced. Before I run down to Star Ford and lay down $95 can anyone verify my conclusion?
Thanks, LLL
