Oleyellar

87k miles. Has high flow cat I believe and full exhaust and injen turbo piping. Getting codes p2187 for system to lean at idle and p013a for O2 sensor slow response rich to lean bank 1. She shutters slightly at low rpms and isn't making more then 10lbs of boost. For the most part it's not running that bad. Something isn't right though. Anyone here experienced these symptoms?

I get P013 fairly often, is usually associated with the defouler tube being too long on your downpipe. Not really an issue with it, just the annoyance of the light. Because of the length, it doesn't pick up change fast enough and will throw the CEL. As for the other code and low boost, not sure on that one. Do some searching of the forums, more than likely someone has experienced that same code and the responses may be of some help.
