I had my 2002 Boxster 2.7 base die while idling at a red light. After several tries, it started and ran rough. I limped it home. Read codes of 300,301,302,303,343. Cleared them and restarted and still shows 343 camshaft position sensor bank 1 exceeds value. Still runs rough. Durametric has cam deviation for both banks as 0. Actual value for camshaft bank 1 is 0. Actual value for bank 2 is -12.92. Can anyone tell me what these numbers mean? Could this just be a bad cam position sensor or is there something else I can check?
