What do yall think my 1993 Ford Ranger XLT 2 wd 4.0l v6 with a brand-new long block, every part on the engine is brand new, new fuel pump/sending unit all new lights, power everything works as it should replace with all new parts, completely rebuilt 5 speed transmission, need tires, and someone to get the engine running smooth is worth? Fires up every time, just has a really bad jerk to the engine and no power and jerks harder under any kind of load.
