i have a 1995 gst with a 18g turbo i just recently had the head rebuilt with everything new put in it a few days ago i started playing arount with it and i capped off all of the vacuum well all the vacuum that was on the throttle body and when i started the car up it runs fine just a slight decrease in vacuum i went from 20psi to 18psi i started to drive well about a mile or so in it sounds as though i threw a rod and i go and park it check it out at idle its still fine but when i accelerate and hit 3k rpm to 5krpm it knocks i'd appreciate anyones and i put the hose back on from the selenoid to the valve on the egr i read that can affect but it still knocks thanks in advance guys
