smog testing issues
2000 Boxster S, approximately 34,000 miles and I’m having problems passing CA smog.
A few months ago I had a MIL showing the P1128 and P1130 trouble codes which cleared with a code reader.
Last week the testing center revealed P1128 and P1130 trouble codes are now classified as passive (no MIL light) and that the catalyst monitoring system was not complete.
I cleaned the MAF, drove more than 200 freeway miles one morning and took it to the testing center. Now it’s throwing evaporative system and secondary air systems not complete errors’ the P codes are gone as is the catalyst monitoring issue.
Any insight helping to address these issues is appreciated.
Looking at the Drive Cycle restoration sequence offers little hope since I live in an urban area with stop signs and lights at every corner.
