If you can operate the engine to bring it to normal operating temperature, the ohm readings will be more accurate (the following readings are for a hot engine). For the pick up coil (magnetic pick up assembly), connect your ohmmeter...

Hi there. Typically when the oil pressure changes based on the type of oil you are using, it's an issue with the pick-up itself. Quite often, the wrong sized or style of oil pump or a pick-up line that is...

You should first identify if the vehicle has California emissions or not. The difference is one will have a mass air sensor in the air cleaner and the other will have a MAP sensor mounted on the a/c evaporator case...

The entire column may have to be replaced (https://www.yourmechanic.com/services/steering-column-replacement).

The testing you did using the CIL may not have been done correctly. During these tests you will need to cycle the clutch and accelerate the engine when the separator codes were received. This is done with a superstar 2...

Do you have a Ford hydro-boost system? If so, faults in that system can cause no or poor pedal return; to resolve the issue with a hydro-boost type system, please refer to the detailed diagnostic decision tree in the factory...

Considering everything that's been replaced, the most likely cause of this issue is faulty wiring or a loose connection somewhere on a part that has been replaced. My best recommendation would be to go over everything that has been replaced...

It sounds like you may in fact have a blown head gasket. A blown head gasket may cause a number of different symptoms. A head gasket that fails between cylinders will generally cause a misfire and potentially compression leaks from...

If you have the ignition switch out of the vehicle then you may be getting a switch that is not making good contact internally. I would first recommend replacing the ignition switch and checking connector for any problems in the...
