My truck has a 5.8l engine and an e40d transmission. Runs great at 2000 rpm but starts to buck at 1900 if im cruisin. Just put a brand new msd distributer on it with new wires, plugs fresh oil and oil filter new idle control valve. T/p sensor new speed sensor, and more but it only does it in moist weather what would cause this.
have the same problem?
