No and No...And it's the "MAS". "Unhooking" the MAS will place your ECM in the "limp back" mode...in other words it will run like ****.
Did you try the O2 sensors (3)? These are notorious for failing. Try a cheap fix...Buy a can of "SeaFoam" at Advance Auto Parts ($9) and add to your tank per instructions.
Good Luck

SOURCE: Have a 2004 Chevy Silverado need some help. Where

95% sure manufacturers place the knock sensor on the intake manifold-it's where the knocking happens-(fuel/air mixing). Mine was on the driver's side of the intake manifold between ports for cyls 4 & 6. Just below the fuel rail- two wire sensor.

Hope this helps!

Under intake manifold on top of block,you need to remove intake to access sensors there are two of them you can't miss them when intake is off. After replacing sensors you need a new intake gasket.
