2.5l to 4.0l Throttle Body swap problem! No idle and Revs goes straight to Redline!
So I just swapped out my 2.5L throttle body and put in a 4.0L throttle body. everything went in smooth and everything is on tight, and I used the original sensors but when i turn the key and start the car, the revs just go straight up and doesn't stop and i shut the engine off right away. I checked the the flap and its staying shut. I'm no mechanic and i don't have a clue why it is doing this. Any help would be great.
