Q: Engine shakes, shuts off 1992 Volvo 740
The car had some minor issues such as shaking at idle. I had an oxygen sensor replaced. I figured that would fix the problem, but it didn't. The other day, I was driving and it started shaking again and shut off completely. There is now a significant engine shudder each time when I engage the throttle. It works better after cooling down. What might be the cause of this?
