Alright i got a 2002 dakota with 4.7 manual transmission.
As I was leaving the city dump the truck start to idle really high. Had to keep turning off the truck just to move forward.
For what ever reason the engine wants to stay at 3500-4000 rpm until the engine get to temperate and tries to stall out, then recovers back to 4000 rpm. Then back and fouth stalling to high reving. On the side of the road I tried unplugging the IAC and TPS and the truck did the same thing. unplugged the battery for an hour for the ECU to reset same thing. Removed the air filter and plugged the air path with a piece of wood so I can hear any vacuum leaks, no leaks heard but did not even effect the engine rpms.
Got the truck towed home and one of the drivers knew for of a master dodge guy and asked him what was wrong and he had not ideas.
My guess is a fired my engine harness because i smell electrical burning. But I am going to start with voltages to my sensors and ohms readings on the sensors. I will start the engine again when it is completely cooled down. I have heard of GM's doing this but the ECU reset works everytime.
Any advise would be great.
