Thanks for the reply, Bronc...I went through the engine looking for vacuum leaks last The pcv hose was fine...
finally got frustrated enough to take it to the dealership. They ran diagnostics on it, couldn't find any codes (like I said when I dropped it off) and couldn't replicate it (I told them it was intermittent). But they took the time to research the situation, and found a TSB on it where the PCM needed to be reflashed because it wasn't recognizing the throttle position sensor.
All well and good though...I let them flush and fill the tranny while they had it (screwy sealed transmission on this Explorer). When my wife and I pulled out, she was actually accelerating away from me, until my truck kicked down a gear!
