Okay well i replaced every ignition part including wires cleaned and got new grounds etc. found out that it is the ECM. now could i just go to my local dealership with my old ecm and have them reprogram it? or do i have to buy another one and give it to them? how exactly does that work. i have a 94 camaro z28 manual 5.7l

 

thinking about purchasing this if i need a new one Cardone ECM/Engine Control Computer 77-8051F-UNF at AutoZone.com

 

just curious, how did you verify that it's the ecu?

 

the mechanic said it was...thru a process of elimination. i dont trust this guy at all. im going to take it to the dealership and just have it done professionally
