Car will sound rough at stop sign, and die out right after I leave the intersection. My dad says that it sounds like maybe fuel pump or idling issue, only does it if we have 1/4 or less gas in the car, anybody with suggestions contact me please!!!
I had a tune up. Air filter change .Oil filter. Change .Spark plugs. Spark plug wires.replaced..about aweek later my car started backfiring..and hesitating at stop light or stop signes.. the mechanic replaced the spark plugs..it still did the same thing..
