And do i have any other options besides actually replacing the ecu??? that is very expensive...

send me your harness and ill redo it. 9 times out of 10 the harness has a faulty lead. make sure, too, that youre tightening down the ECU plug ALL THE WAY!! so many people think they tightened it down when in reality, they havent. tighten it down and then push the ends in.

 

hoe much would you charge?

 

what year car, which motor?
