The CEL light was on when I picked it up with the following codes:
C0223 Right Front Wheel Speed Signal Erratic, ABS$29 (history)
P0161 Oxygen Sensor Heater, Circuit Bank 2, Sensor 2, MOD$10 (confirmed)
P0300 Random Multiple Misfire Detected, MOD$10 (confirmed)
P0161 Oxygen Sensor Heater, Circuit Bank 2, Sensor 2, MOD$10 (pending)
P0300 Random Multiple Misfire Detected, MOD$10 (pending)
I cleared those and drove 25 miles No CEL, parked let it sit for 10 minutes started it up and the CEL came on with the following codes:
C0223 Right Front Wheel Speed Signal Erratic, ABS$29 (history)
P0161 Oxygen Sensor Heater, Circuit Bank 2, Sensor 2, MOD$10 (confirmed)
P0300 Random Multiple Misfire Detected, MOD$10 (pending)
I?m not sure how they checked the cams they mentioned having the valve covers off.
