2007 Ford Focus Repair Question
My Focus hesitates and loses power and has engine code on.
After 4 weeks, the car did the same thing again, again on an 89 degree day with air conditioning and cruise control on. Stopping for a few minutes restored power and cooler weather seems to eliminate the problem.
Could the problem be the fuel pump, when it works fine all but in heat situations?
Could there be a plugged air intake/air filter, or a sensor that would cause problems only during hot weather with engine under "load"?
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.
