So the problem is the MAF or the Knock sensor ?

 

its the maf. easy way to tell peck on the maf sensor when its running or wiggle it and it should do it i know mine does. it messes with the reading of the maf sensor and it does it more so when u put a hard intake pipe on the turbo.

 

test and tune day at the track. i bogged the launch from an open header V-8. fail.
