My car has recently stopped running. It has also been stalling on the freeway, and shuts off when I turn on the headlights. I did all of the basic troubleshooting, and it’s not the alternator, battery or starter. Check engine light shows ecm needs to be replaced, but I just replaced it two years ago. My question is: could I just reprogram the ecm that I already have, or do I need to get a new one?
My car has an automatic transmission.
