OK guys...sorry for the delayed response but the problem was found and corrected. Turns out the original dealership WESTGATE CHEVROLET installed and aftermarket MAS. This faulty AFTERMARKET part was the perp all along and hte 2 grand additional I spent was down the tubes....
GM customer service did refund the cost of the part but no compensation for additional expenses even though the aftermarket MAS installed by the dealership where I bought the car was faulty and not to mention they kept it for a week after they installed it and never thought to check it out.

Needless to say my business and my referrals are going to the dealership that immediately found and correct the problem. ( GREG LAIR)
