when cruising, the car every once in a while will have kind of a stumble/spit and sputter to it, i put new plugs in it yesterday, champion 12yc's gapped to .30, the wires are like 6 months old they are bosch wires, has a new mopar HEP and mopar coil (few days old) and cap and rotor are also like 6 months old. i re checked the timing and it all looks good, and looked at with the timing light and on about 12.-12.5. i ordered a new fuel filter today. to change that. but other than that i dont have a clue. and its just while cruising. under boost all seems fine.
