Engine problem
1991 GMC C2500 V6 Two Wheel Drive Automatic 190000 miles

I have a 1991 GMC full size Vandura Van with 4.3L engine and TBI fuel injection. Been doing some work trying to get it ready for a trip home this month. Van runs well but I have noticed a decline in gas mileage over the past year. Replaced the plugs, wires, cap, rotor, air filter, fuel filter, PCV and while I was doing all of this, I noticed fuel dripping from both injectors with the engine idling - is this normal? Spray looks normal when I hit the accelerator, but I don't know if I have ever noticed fuel dripping at idle?


Do you
have the same problem?
