whats wrong with my gst

[fixmy97gst]

I have a 97 gst with a sporadic hestitation and a usual choking out around 4000-5000 like it's missing under a load...another guy has a 96 gst doing the same thing...I have new NGK ( blue wire) and new NGK plugs..a New crank angle sensor as well a new cam sensor..it's been doing this since I bought it used with 72000 mile on it ..It now has 101000 on it and Mistu can't tell me whats wrong with my car....so if anybody has a sugestion, I'd would be grateful

Your best bet would be to do a boost leak test.

How do you do a boost leak test....it also sometimes act like it's running on three cylinders that some times clears up if I pump the throttle while acelerating...
