When using the Archer's feint trick shot, you would use the bluff skill for the check, as feinting is not a combat maneuver and thus doesn't use your CMB. A strict reading of the text would mean that you don't take the -4 to the check for attacking ranged.
For other commenters, Vega is referring to the third level ability of the archer archetype of the fighter class:
Trick Shot:
At 3rd level, an archer can choose one of the following combat maneuvers or actions: disarm, feint, or sunder. He can perform this action with a bow against any target within 30 feet, with a –4 penalty to his CMB. Every four levels beyond 3rd, he may choose an additional trick shot to learn. These maneuvers use up arrows as normal.
