Last night my motor was running awesome, today i went to drive the car to school and it seemed to idle fine under 1000rpm but it had a wierd shaking when accellerating and you could definately feel in in the gas pedal, i think it had slight power loss, hard to tell for some reason, but i found a plug wire that had some of the insulation burned off by touching the header, could it be arcing against the block or header causing powr loss or could it be something else?
