O2 sensor problem

It will impact your emissions and you gas mileage to a little extent and it will get worse over time, although not all that quickly. It won't effect performance because the PCM doesn't use them when you're running the car hard.

You could try pulling the one indicated and cleaning it off a bit. You can't do much because you don't want to force a replacement :) and because whatever is on there is pretty tough since the sensor gets pretty damn hot. I wouldn't dip it or spay it, although I know folks who use brake cleaner and it seems to burn off clean, but you could brush off anything flakey. I've read of using a propane torch and a brush, as well.

Propane torch is a sure way to have to replace the thing... Get a butane cigar lighter (the ones that have a blue flame), and use that to burn off gunk without ruining the sensor.

i call BULL CRAP

the pcm goes to a preprogramed mixture rate and uses other senosors in place of 02 sensors the mixture however is generic\
