THis problems has been annoyed me for years, and now that inspection has come around I can't pass any of the tests. Especially considering that every time I reset the codes, I have to complete a drive cycle in order for it to be ready for inspection.
P0133
O2 Sensor
CKT Slow Response
(Bank 1 Sensor 1)
P0420
Catalyst Efficiency
Below Threshold
(Bank 1)
Those are codes, I have already replaced the front o2 sensor but it really didn't fix the problem, cel popped up less than a 1000 miles after It was fixed. I have a RT high Flow cat and Focus Sport SCT tune. You guys have any solutions? I dont really want to spend the money for another o2 sensor.
