i have a 1992 100CS automatic (not quatro). the car just a few days
ago had a fuel pump and filter replaced. it ran fine...until now. i
was going downtown and hit a large pothole (there is construction and
they are tearing up the roads). after i hit the pothole it continued
to run fine for about 10 minutes. after that i noticed it was running
kind of rough and didn't accelerate quickly or seem very responsive.
that continued for about 5 minutes. then i parked the car and turned
it off. when i turned it back on it started but ran very rough and the
rpms lowered. that continued for a minute and then i shut it off and
had it towed home. i checked to see if it was the fuel pump and there
was pressure in the lines. i looked under the car and i see where
something hit, but it hit the frame, not the fuel pan, exhaust, or
such. i don't know what happened. any help would be appreciated.
