wire, just change the one for now to test, then throw them all in new

it was the plug wires, when i change dmy sparkplugs i noticed electrical tape on one of them but it didnt feel broken underneath, then when cylinder 3 was misfiring and it turns out that cylinder 3 was the wire with the tape on it, i looked under and it was allc racked and desintegrating, got new wires and its fine

I had the EXACT same problem this past April, the car started shuddering bad, major loss of power, NO SES however. My one MSD wire was carbon tracking bad.
Simple stuff is nice cause its cheap.

I tihnk whoever changed the plugs last screwed it up and left it touching the header or something cause 2 of the 3 front plugs werent in that track by the crankcase and were loose. i bet it touched the header or something and was taped up after
