Ecm code H 18???
Hey guys...I did the paperclip trick today on the 94 and got the module number 4...Powertrain Control Module...and a code of H 18 if I read it right. I'm looking through the FSM which is a task in and of itself!!!! Still havent found exactly what it is so I wanted to ask CF guys to maybe shed a little light on this. Thanks for any help
