check engine light came on got code with obd2 for missfire third cylinder then I replaced sparkplug, wire and distributor coil problem still there. Car is still driveable just lot of vibration under load. When I got the old sparkplug out (just replaced about 5000 mls ago) their was no discoloration or anything else that looked out of the ordinary. Next thing to replace I would think is the knocksensor if you agree where is it located.
