My 1998 ford explorer, idles rough, stumbles on accelleration, and lacks take off power, once it gets going it s fine, any ideas where to start? Already checked for vacume leaks, bad gas, not the problem
Do you have a check engine light on and when was the last tune-up?
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.
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.
