I have a 2001 Ram 4X4 with a 5.9 liter engine with 180,000 miles on it. When I try to accelerate (especially with the engine warmed up) the engine misfires and backfires. It feels like it is misfiring at 55 mph but not as bad as during acceleration. I have replaced the ignition coil, crankshaft position sensor, ignition wire, front oxygen sensor and added two treatments of Seafoam in the gas tank. I also replaced all of the plugs, wires and distributor cap and rotor in the fall. The recently replaced ignition wire has a slight electrical glow tat is visible from the outside cover (it is an Accel wire) when I look under he hood at night.
I do not have current error codes since I cleared them about 200 miles ago. Can anyone tell me what I should be looking for?
