1997 Ford Contour Repair Question
I have installed new plugs,gas filter,air and crank case filters. I am running premium gas along with injector cleaner and I replaced the 0xygen sensor up stream due to code that was on OBD 2 system scaner after check engine light came on. I have cleared codes and still boggs down. When you are at a stop light it seams like it idels a little high and car shakes and rattles. Doe's this sound like a idle sensor or a MAFS. I'm not geeting anymore codes right now. I'm Picking my brain on this one.
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.
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 and keep testing.
