1991 Buick Regal Q&A
1991 Buick Regal Question: Why does my car run Rough?
I replaced two coil packs, it ran ok. One day I was driving and the car shut off. i tried to start it then it back fired. It started up after 5 mins or so. It drove home fine. I was driving it the next morning it was running rough. I thought it was the other coil pack that needed replacement. I did that, but it was the same. I replaced the wires, still the same thing. What do I do now? - Visitor
