1990 Dodge B150 Base 6 Cyl 3.9L
Backfire alternator and voltage regulator have been fix along with tune up and still backfiring. black smelly smoke too
and i changed the oil and filter and now it stalls , mainly when coming to a stop. it never has stalled before the oil and filter were changed then it started right away to stall.please help if you can on both problems.. thanks...
Black smoke is indication of unburnt fuel, is it fuel injected or carbourated? EITHER WAY HAVE CARB OR INJECTORS CHKED...and back fire is usually caused by a timing issue
