revving problems


For some reason my 93 5.0 will not rev past 3000 rpm. If I feather the throttle in neutral in will but it is rough. Will not do it at all in gear. Does anyone know where to start looking for the problem?

Have you changed your fuel filter, sound almost like it starving for fuel, maybe weak fuel pump, but this is kind of a wild guess with out know much more.

It might have vac leaks. Is its VSS sensor working properly? Check it once.
