Truck stalls at idle, or near idle, speeds. Also surges at cruising highway speeds. Replaced egr valve, pintle position sensor, TPS, Ignition module, Distributor, O2 sensor, MAP sensor, EGR solenoid, PCM(rebuilt) and a couple of vacuum lines(dry rotting). Cheked for other vacuum leaks(none found), Checked timing at Idle with spout disconnected(ok except the timing mark bounces around alot from the stock 10 degrees mark). Checked fuel pressure 2 times(once by me and then at ford also) and its okay. Cleaned fuel system numerous times. Cleaned throttle bore a few times. I am stumped! Can anyone help?
have the same problem?
