Went to Autozone with my 1996 V6 to get the codes read. The CEL has been on for about 2 weeks. He pulled two codes:
133: O2 sensor slow response, bank 1, sensor 1
420: catalyst system efficiency below threshhold
He said if the catalyst was plugged, that could cause the O2 sensor code. He didn't know if the O2 sensor problem could cause the catalyst code. Autozone can't test the O2 sensor but apparently it can be tested to see if it's bad or not.
What do you think, gentlemen? BTW, the engine is running fine so whatever it is hasn't affected driveability.
