98 XJ 4.0 180k - runs rough at low rpm
Just replaced fuel pump, all injectors, plugs, wires, dist cap, rotor, and main coil. However it still runs rough as soon as I shift it from park to drive. It accellerates ok but it feels rough not smooth like before. It seems to go away a bit if I punch the pedal or once I get to highway speed. What could it be?
No CEL either...

Try cleaning out your throttle body and IAC. Only cost is a can of throttle body cleaner.
