2002 Malibu Rev/Surge - ongoing....
I now have a re-man ECM/ECU in my possession. Two different avenues of advice have been received concerning it. One is to take it to the GM-dealer and have them re-flash and have a trustworthy auto-electric tech install it OR take
the unit to the dealer, have them install it and then re-flash it. Any suggestions?
2002 Malibu follow-up....
I have brought it to a dealer, an auto-tech and a "Precision AutoTune".
No luck in retrieving any codes. None have been read. No "service engine
soon", only the rev/surge/chuggle of 100 to 300 rpm at highway speeds.
I suspect it does not last long enough to code. Even when the tech was
on the road with a partner and reading his scanner, they did not get any
readable code, yet he said it did it often enough to kick the vehicle out
of cruise-control. Thus far, we are all stumped. I will go on the Chevrolet
Forum and see what I can find out there. Thanks for your input. I will not
be a bother here again. Ciao.
