you have a vacuum leak without a doubt. idle pressure should be roughly -10.5psi, not 9.

your actual afr is very rich, which is why your trims are off. they should be 14.7

possible causes:

dead MAF sensor
dead o2 sensor
big leak somewhere between the turbo and manifold (check ur bpv)

i have the manual at home, when i get home from work ill take a look

well i checked the bov it was to loose on the setting that fine but what will make it eat a spark plug. any ideas maybe a intermite stuck injector ?

running rich, like you are, can foul plugs very quickly
