I have a '99 4.0 5-speed that has a flat spot or hesitation from 1200 or so RPM. One I get it to 2000 RPM it is fine. Very occasionally I also get a backfire at this RPM when I nail the throttle. I've already changed plugs, wires, cap rotor, air filter, and voltage tested the TPS.
No OBDII trouble codes or pending codes are present in the computer.
Any ideas????
