2005 Other Lincoln Models V8 All Wheel Drive Automatic 68000 miles
While driving the vehicle hesitate, skips or hiccips as if it wants to change gears even though it is an automatic. First I was told the vehicle was misfiring and the coils needed to be replaced - this was done problem still exits. Next I was told the Mass Air Flow Sensor needed to be replaced. This was done - problem still exists. Any thoughts or ideas
Hi jlcgac, Welcome to 2carpros and TY for the donation-this is what keeps the site going.
Lack of acceleration, chugging, hesitating, jerking, bogging, misfiring etc. Could be caused by one of the following below: Oxygen sensor.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Manifold absolute pressure sensor.
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.
