at idle with truck in nuetral it runs smoothly. has new plugs, cap, rotor button.
my 1994 ranger runs rough under acceleration. on 1994 Ford Ranger
you never said if you replaced the plug wires if not I would get someone to load up the engine and spray the wires with water to see if you have a wire arcing
Plug wires solved the issue...thanks
