1992 Buick LeSaber Custom
Dear MW: My Daughters Buick chugs and will even die on her.
I just put new plugs in and that didnt help any. so i poured a bottle
of injector cleaner in the tank and drove the car for about 5 miles and that seemed to
help some.
What would you suggest I try to do next? What else should I be looking at? Thanks for
your help.


MW:
What you are describing could be several things, but a common problem is that the fuel
pressure regulator is leaking fuel into the vacuum hose, causing a rich condition. Another
symptom is that it cranks long until it starts, then runs rough for a few seconds, then
clears up, may die at stops.
I would also check fuel pressure, and check to see if it is missfiring.
