Ford Escape 2007 200000 miles
I own a Ford Escape 2007, 3.0 engine and it is presenting an engine failure, a kind of trembling as though electrical current could not reach it. This trembling gets worse when it is stopped or as I drive along an uphill road, when above the 4000 rpm. Coils have been checked and no failure was found. I was told the cause can either be the injectors or the catalytic converters, what do you think?
