1991 Mercury Capri Repair Question
How can i fix my car that cannot maintain speed when it reach 2100 rpm.
Please help as I already change mostly everything like Air Mass Flow sensor, spark plugs, wires. fuel pump, fuel injectors, ignition coil, air filter and fuel filter.
Do you have a check engine light?
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.
