Default Hmm.... lots of codes. Have you cleared them to see if they come back? If so...

looks like:

ABS module either gone or on the way out

Drivers side secondary O2 is gone

Possible boost leak

Pass side secondary O2 is gone as well.


Seems like a lot of intermittent codes. I would clear them, and just make sure everything is well connected, etc. If they are gone they will come back pretty quickly (50 miles or less).

Also pressure check for sure.

Default AWE has a good write up on the tester.

Don't know about the ABS but you might search the archives. I know others have had similar issues.

Might be your TBB or some other leak. Hows the car running?<ul><li><a href="http://www.awe-tuning.com/media/pdf/27t_pressure_tester.pdf">tester</a></li></ul>

Default I would still pressure check to make sure you do not have a leaks somewhere but outside of that...

I would most likely take it to a shop on the positve deviation code. Or Search the archives for more info.

The O2's are DIY

and the ABS pump can ususally be rebuilt by module masters.
