2009 Toyota Camry 237000 miles, 2.4 liter automatic. Woman had the oil changed and battery replaced. Started running poorly, no power. Codes were misfire cylinder 1 and p2238 air fuel sensor. Replaced plugs and coil packs. Cylinder 1 plug was soaked with oil. Now the car idles fine but runs poorly in drive, no power. Should I replace the sensor or do you have an idea what could be wrong with this car? Any help would be appreciated.
Cylinder 1 plug was soaked with oil.
Electrodes, or just the outside of the plug?
Should I replace the sensor or do you have an idea what could be wrong with this car?
Have you performed diagnostics to determine whether the sensor is bad? Is there anything suspicious in live or freeze-frame data?
