2002 Mercury Cougar
Why is my 2002 Cougar sputtering?
Sunday, November 28th, 2010 AT 2:57 AM
Lack of acceleration, chugging, hesitating, jerking, bogging, misfiring etc. Could be caused by one of the following below
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.
Note: If it doesn't apply disregard it
