Hi,
I have a 95 Buick Lesabre. It occasionally stalls. It will run bad/die for a few minutes then be fine for a few days. No codes show up and my mechanice couldn't get it to stall. He did say the cooling fans were kicking in even when the engine was cool. He believes the ECM is bad. Also the outside temperature screen flashes when I start the car.
My mechanic said I would need to bring it to the dealer to replace the computer, because they would have to flash a chip in it.
Can I replace this myself? Autozone has the computer for $99. From what I have read on the internet, you can take the prom out of the old computer and put it in the new one. Is that the case?
Thanks chad
