99 sable bad PCM?
I have a 99 sable OHV 3L. It has a misfire on cylinder 1. Coil pack, plugs, wires and injector were changed, the fuel rail system was cleaned. Don't notice the mis when I drive it. I was told it could be caused by bad PCM. It now started to develop a trans problem. When the [LINK REMOVED BY MODERATOR] speedometer reaches 40 mph, it goes wacky then stops working. Soon after that the trans starts to slip once and a while. My question is can all this be caused by a bad PCM? Thanks in advance
