Ah, the Burgundy Potato saga continues!
This doesn't happen all the time, but I've had 3 instances in the past week where this happened - I'll come to a complete stop (or 1 time I let off the brake to press the accelerator to merge into traffic) and the RPMs will dip down from idle (700-800ish) to below 500 and almost feels like it's going to stall.
Some back story -
One day I drove 20 miles away, parked for a few hours and was getting ready to leave. I turned the car on with no problems. Then about 30 seconds of idling the orange wrench came on. I was thinking it was linked to my other issue (http://www.explorerforum.com/forums...r-maybe-torque-converter-clutch.372634/page-5) so I wanted to drive it long enough to hopefully have a solid check engine light. Got home, shut it off, turned it back on - orange wrench gone... wtf.
Got up the next morning to leave and the orange wrench again, only this time it was accompanied by the CEL. Drove to Autozone to have the codes read. It was determined that it was a Throttle Positioning Sensor. This is funny since I replaced the entire throttle body with an Autozone unit since I completely F-ed up my OEM one. The Autozone unit came with the TPS and all the other bits and pieces. Meanwhile the RPMs dipped low enough for it to shut off while in the parking lot. Started back up with no problems.
Later that night I moved the car to my back driveway and the Explorer failed to accelerate. I had the gas pedal pegged to the floor and it just creeped and crawled. When I went to round a corner the drivetrain sounded awful. It sounded like the brakes were popping on and off all on their own. Eventually it completely stopped even with the gas pedal all the way down. I turned the car off and back on and I regained all power.
The next day I replaced the TPS sensor with the one I had on my OEM throttle body and everything was back to normal except the few instances where the car felt like it was going to stall out.
Anyone might have any ideas where to even begin???
