Anyone have any idea on what could cause throttle stutter? My trucks an early 04. Around 1800-2100rpm the truck will jerk rapidly. My tuner says my pulsewidth is being erratic. Something is either causing the tps signal to drop in and out quickly, or there's interference. I've replaced the tps with a timbo unit, replaced both cam and crank sensors, and added the bd diesel ac noise isolator with no luck. When I set my meter to ac voltage and test the alternator, I get 0.006V, so I think that's fine. I haven't found any damaged wires and I have no idea on where to go next.
