Re: O2 sensor - trick

I have a slow responce for my sensor. I tried switching it the other side and the code followed the sensor so I know it is that and not the wiring. Maybe I could try some electronics cleaner on it? Or should I use starting fluid?

I've cleaned them with a MAPP torch before when they got fuel fouled and all carboned up... worked great, and I'm still running those O2s 10K later...

not sure why this is like that maybe because there isn't enough history? I reset the PCM not to long ago for air pump issues. please some one explain these short term trims to me

EDIT* Just read on AT it maybe due to canister purge. Normal.

so I guess I will be keeping a eye on those. hopefully thats why its like that
