1990 chevy silverado running rough and dying after road test
She sat for two years before I bought
it. I've replaced the fuel filter, air filter,
oil change and oil filter, spark plugs,
and battery. When going in reverse, if
you put very little pressure on the gas
to back up slow it will start to chug
and run real rough and eventually
die. The same thing happens while in
drive as well. While going at low
speeds and I let off the gas it starts
to chug and want to stall before just
barely catching itself. Runs great on
the highway. However, 80% of the
time I pull into a parking lot or gas
station after driving for 15/20 minutes
or so it'll die. I'm kinda stumped on
this problem, any ideas?
