RE: emission system service
Thanks Tech, I took it to my mechanic & he ran a diagnostic on it, came up code P04020, which is catalytic below threshold. He said it's either the catalytic (which is still warrantied) or a bad O2 sensor. Volo said it would be abot 300 to replace the sensor. Does that sound reasonable?
