Hi Guys,
Even with my shop not being sure about MAF, I have ordered a new one. I seemed to have bought someone elses problem car. I hope the Secondary air and cat eff. codes will clear with the new MAF...and maybe the PSM/ABS codes, but I don't think so.

 

Thanks to everyone who helped me with this. I think the Durametric is the best tool anyone can have when you own a modern Porsche. I used it again today and found I have dead O2 sensor after the cat. This should fix the cat eff. code I have when I replace it tomorrow. I still have a secondary air code...maybe it will fix it also...any thoughts?

 

Look at changing the front psm looms there is a chance that they were damaged with the pss9 install, this may be the reason why you are getting the psm abs light. Should be cheap.

 

I have put this on the lift and looked at all of the wiring 8 or 10 times by know and haven't seen anything at all...With the evap problem now fixed I guess I will start changing other parts to fix this...
