I have a 2004 3.0L V6 Edge.
Just recently the Engine begins over revving when I push the clutch pedal in. that is when the engine begins to over rev, slowly climbing. When I come to a stop a second or two the engine over revving returns to it's resting idle speed.

Just did a search to see if there is something like this happening to others and have not found similar idle over revving issues.

Any Help appreciated.

Well manual transmission Rangers should "hold" RPMs when shifting, and RPMs should stay above 1,200 until speedometer is under 5MPH
That is normal, it lowers emissions.

The "holding" RPMs should only last 5 to 10 seconds, so if you leave clutch pedal in while above 5MPH the RPMs should drop to around 1,200 after 10 seconds.

I would first test for a vacuum leak
Warm engine up to operating temp, and let it idle, should be about 700rpm
Unplug the IAC(idle air control) Valves 2 wire connector, valve will close and RPMs should drop to 500 or engine may even stall, either is good it means no vacuum leaks.
If RPMs stay 700 or higher then you have a leak.

Also get your VIN(windshield plate or drivers door sticker) and call or stop by a local Ford Dealer, give them the VIN and have them see if there is a newer Software for your 2004 computer, there were some models that had revisions to the software because of your symptoms.
You would have to pay for this fix in most cases, but you won't solve the problem without it so..........

 

Thanks RonD. I've got some direction to check, thanks to your info!
