The actual numbers are approximately 10.1% CO and 600ppm HC (from memory i dont have the results here).
Ill try the fuel aditive and test the TPS first off, and see if he used solder and what brand of sensor it was. I remember on my car the ceramic element in my new universal o2 sensor broke within a year of use.
Ill try the AFM screw next and then i guess the FQS after that. How will changing those settings affect the loaded portion of the test and the driveability of the car in the mean time?
I still work at the Porsche repair shop part time, but this is a friend who i'm helping out for free. that means no borrowing the exhaust gas analyzer and i'm also not asking my boss the guru any questions, since i've recently started a separate shop with an entirely different focus, but still i don't want him to worry i'm trying to beat his prices with HIS customer base. Which i'm not. So i'm relying on trusty old pelican parts, which has never failed me
Thanks for the excellent advice and the overwhelming amount of helpful links
