Unplug MAP sensor Unplug EVAP solenoid (Picture is 5.3 L, the 6.2 {L86} is on the throttle body) Pull the wire-harness off the Plastic intake cover. Remove Throttle Body (4 bolts) Or disconnect Throttle Body wire. Remove the intake manifold bolts 1/4 turn at a time until you can loosen and remove by hand. (see diagram for pattern). A little trick for the number 7 Bolt, get a deep well socket and place on bolt, then put the ratchet on the socket and loosen. When re-installing the manifold follow the pattern in two torque specs.
