Cel keeps coming on
I have had many sensors replaced on my lexus rx300 including all of the o2
sensors! The CEL came on a week after having them all replaced so I took it
to have it anylized and it said o2 sensor bank 2 sensor 1 bad again. Took it
out and cleaned it the light stayed out for 3 days and back on again! I have
done this several times and before the light comes on it lacks power! After it
comes on power returns. My question is what could be causing this issue? I
would like to resolve it once and for all!
