1989 Chevrolet Truck Repair Question
1989 Chevy Truck engine bog
1989 Chevy Truck V8 Four Wheel Drive Manual
My truck runs and starts great , however it occasionally bogs down then will come back and drive fine. Sometimes it does it 6 or 8 times for a 10 mile trip sometimes not at all. I have had it bog down and not straighten up then it stalled. It did start back up and drive fine. Ive had the plugs , wires, fuel filter, cap and rotor replaced and fuel injector cleaner placed in it. I love my truck ... Can anyone please help me figure out what i need to do to get it running up to standard?
