A few months ago when I moved to Reno I picked up a 1994 Buick regal 3.8. Overall for what I paid for the car I don’t have much to complain about.
One thing is driving my crazy. As I’m driving there seems to be some minor bucking, almost like having bad gas).
I took the car to Buick for a diagnostic and they game me a list. I picked up all the parts myself and had my mechanic do the work.
PCV valve
Plugs
wires
Serpentine belt
O2 filter
air filter
Oil change/filter
And no guess what? It’s still doing it. It’s very minor and I may be the only one that feels it but it’s there.
I was thinking it could be the catalitic convertor, or maybe fuel injectors. Both aren’t cheap.
Does this model have any history of problems such as this and should I even worry?
