I finally got my zc dropped in my 90 rex! Had no problems thanks to jlicrx! Thank you much! It runs fine all day until I get down on it and right as I shift into 2nd, it pops a code 3. I can reset it and have no problems till I'm runnin it again. Can anybody help me. Do I just need a new map sensor or a pm7? Thanks for the help!
