I changed the fuel rail and line ad o-rings (had a leak at the rail) truck ran perfect with none of these symptoms before I changed it. Also I cleaned the TB (hosed it good) while it was off. I have changed all the sensors on the tb and still no luck. It revs up about 500 rpm when I let off the gas and bumps hard when i shift into gear now. Got a check engine light that gives the code 22 (temp sensor bad) Is this realy the problem or am I missing something 94 Dakota 4x4 5.2

 

Yes it can be the temp sensor. There are 2. One 1 wire for the gauge. One 2 wire for the computer. Change the 2 wire.

 

Cool, thanks. i picked up the part today and wondered why it had 2 prongs. Where is the 2 wire located?

 

Both are next to the thermostat housing.

 

Found the problem. The harness came off when I did the fuel rail Thanks for the help Crazy.
