Seems to still vibrate at idle, but ran fine after clearing codes, no SES light in the short trip to the gas station and back.
The codes before I changed the plugs:
E3 - Oxygen Sensor adaption limit Cyl 1-3
E4 - Oxygen Sensor adaption limit Cyl 4-6
EE - Misfire cyl 1
F0 - Misfire Cyl 3
EF - Misfire Cyl 2
CA - Oxygen Sensor control limit, Cyl 1-3
