the Quad B fault went away
but i still had the Quad A Fault
so i disconnected the Vacuum line going to the BCS and Cleared the Code and it didnt come back
one problem now at full boost is Misses could that have something to do with the BCS not being hooked up
BTW tune-up was perfromed recently plugs wires
Could the miss be the Knock sensor pullin timing?
no other codes came out
you can hear a slient miss at idle i checked wires and they are all on
