1990 Volvo 740 Questions
could this be vac leaks or is it map,o2,sensor related? fuel pressure? also will occasionally buck while driving at interstate spd. there is no check engine light on also the speedo has become erratic and the anti lock light is coming on after hitting a bump and now stays on longer/more often
It just hit the 20000 mark could it be something in the drive shift, is it hard to change the bump stop.
I pulled the head and there is a hole burned through the top edge of the piston.
