Bad engine
Well checked compression on my engine myself to verify what I was told at the dealer and unfortunately for me they where telling the truth the engine is in tough shape found 3 cylinders that had very low compression these engines just don't seem durable enough to me hear way to many people with them replacing engines at 100000 miles or less this I just unacceptable ford should b ashamed for releasing suck a poorly designed engine there got that rant out anyone know of a good place to get a long block
Have u checked the injectors? Bad compression can be caused by a bad injector bleeding the pressure.... Just an idea
My motor was replaced recently after only 76,000. I threw countless sensors, replaced all plugs, injectors, coils, tried custom tunes, etc.. tracking down a hard misfire and strange noise under a load. Ultimately I took it to the dealer and there was metal in the oil pan and 11psi less op at the head. Thrust bearing shot. New Engine.
