1998 Malibu 2.4l 4 cyl, start and get acrid smell exhaust. Tailpipe is black w/ exhaust soot..just replaced alternator, engine violent at low rpm ( under 1000 rpm) easily stalls
Start engine, get acrid smelling exhaust fume. Tailpipe is black, engine feels
like it's running on 1 or 2 cylinders at idle ( less than 1000rpm), must feather
gas pedal to keep it going. Smoother running at higher rpm. Must feather gas
pedal up and down at 'idle speed', otherwise will stall out.
also, I should note that there are no check engine light on.
i think i would start with a tune up. maybe some injector cleaner i would use BG44k cleaner
I also forgot to mention that even though the Malibu 1998, it only ha 84,000 miles on it.
