CAR PERFORMANCE

1990 Mazda MX6 • 4 cylinder 2WD Manual • 183,000 miles

90 mazda mx6 2.2 4cyl has hesitating prob and shuts off, like a miss in the engine when traveling down the road not at a stop. Changed fuel filter that eliminated most of the hesitating but after 10 miles it started to hesitate again but not as bad.

Could be caused by one of the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
Fuel contamination.
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.
