Buddy of mines truck, 91 Chevy Cheyenne 1500, 4.3. Its been lugging and missing pretty bad lately. I put new plugs, wires, dist. cap and rotor on it. didnt change the way it ran at all(and the plugs were pretty hit). Anyhow, after changing it I overlooked all the vacs, none are leaking. But what I did notice was the drivers side injector(its only got two) wasnt spraying even. In fact, the back side was spraying, but the front drips. Whats the odds that the injector is the problem, is it possible the drip is causing the truck to flood slightly? What is does it idle rough, and its jerky when giving it a little fuel. Also, when trying to go up slight inclines, its like there is no power. If it will help, Ill post pics of the plugs that came out of it. thanks
