assuming you have an LS1 with OBDII, i would invest in an autotap. if you have lots of miles on her i would at least just pop the MAP sensor and clean it out. also, maybe try tapping on the MAF sensor (gently) or jiggle the connector while the engines running at idle. any fluctuation is usually a sign of a faulty MAF.
It Was A Vacume Leak Behind The Throttle Body,a Little Tape And Runs Like A Bat Out Of Hell
