I had an ECM replacement installed about 4 and 1/2 months ago for my 96 Jeep Grand Cherokee Laredo 2 wheel drive for intermittent stalls at stop signs and while moving. No codes, spent a lot of money diagnosing, replaced ECM and not 1 issue since...until now. My question is what the hell is causing this? Is it an electrical short?
Fortunately, Autozone is giving me a replacement for free, and all they want is the core ECM.
So...my next question is...do I have to get the ECM flashed for my Jeep. Is it only the VIN that is programmed in?
I would assume that Autozone would already have the ECM flashed for my make and model Jeep, but I just want to know also if the Jeep dealer has ripped me off because they told me I needed to have the ECM programmed.
Autozone doesn't know whether it needs to be flashed or not. Their computer has no notes that it needs to be flashed. Unsuspecting people that are replacing an ECM must already know that an ECM requires flashing? Because I sure didn't. I assumed it was plug-and-drive hardware.
