Hello Peter , I want to ask if you or someone you recommend can rebuild OR recondition the ECU on 1990 w126 C , it’s giving cold hard start, I confirmed it’s the ECU after I switched it with known working unit and the car fired up very nicely, so I am sure the ECU causing the cold start problem.
Hi! I have this voltage jumping at ICV pins (1.2-4.5v) while ignition on. Look at the short video I uploaded. Is it capacitors problem? I get 0V when idling.
Great info Peter!
