3B poor running - pretty long

[QSHIPQ at aol.com]

Minhea.  Fixing MM hoses usually allows 6 psi (IME).  After that, it leaks.
The codes you have are from excessive airflow thru the MAF, which would cause
both the error codes you are experiencing.  1.3bar means boost control is
shut down, and you are running at baseline spring pressure.  That means you
either have enough critical errors to shut down the boost control, or you
have a bad WGFV or both.

Make sure you have no air leaks at all, replace the O2 (it's a 60k part max).
 Also ck the WOT switch for resistance.
