High Pitch Whistle
 

OK, Intermiten problems with MAF, so I replaced it with the 2.0 VW Maf. What I thought was a PING from running to lean, is still audible. sounds like a shrill referee's whistle, only at WOT.

I Vagged First codes were Lean, MISFIRE cyl #1&2.
N75 Valve Intermiten.

Replaced Plugs (NGK BPR6E)
Replaced MAF



This Is what I Have.
2001 1.8TQMS
2.5 Custom Exhaust
Turbo XS BPV
Giac Chip
K&N
New Vacuum Lines

I Guess It could be a Broken Intake PIPE.
Any Other Idea's
Thanks
Dave

and tha whista go WOO WOO!
