I had to codes come up today on the car P0141 and P0306

I was wondering since code P0141 might have anything to do with P0306, cause apparently that O2 sensor somewhat runs in conjunction with Cylinders 4,5,6. and P0306 is Cylinder 6 misfire..

Car runs pretty good, and doesn't miss.

p0141 o2 sensor fault- possible replacement needed for your o2 sensor. how many miles do you have? and on your p0306 cyl 6 misfire- have you hooked up a good scan tool with live data to check for misfires? even tho it seems to run good it could have an occasional misfire on cyl 6 that wouldnt be too noticeable. id check that first to see whats going on and go from there
