[s-cars] Codes

[Robert Myers]

Yup, I checked for boost leaks.  The system holds 
pressure.  Suspecting plugs (I had no idea how long the F5DPOR plugs 
have been in the car - they were in there when I bought the car a 
year ago) I replaced them with the plugs used in the A4 1.8t just 
today.  No joy.

I have a new 13913 OXS ready to go in as soon as the 
connecter/harness on order arrives.

The engine starts and runs well until I climb on it a little too 
much.  I'm not stranded by the side of the road but I really want to 
get this solved before heading toward //SFest in about a month.
