4.3v6 Rough Idle
I Have A 95 1500 4x4 With A 4.3l Vortech V6. I Have Replaced The
Plugs, Wires, Distributor Cap And Rotor, Pcv And Egr Valves But Still Have A Rough Idle And Hesitation In Acceleration. The Truck Is Much Better Than It Was, But Something Is Still Needed. According To The Manual, The Timing On This Truck Is Not Changed By Moving The Distributor. Any Suggestions Would Be Greatly Appreciated.
