I just had this same exact problem with my 2008 Chevy Trailblazer 6cyl. 4.2L engine - it was a faulty secondary air injection solenoid - looks like they had to replace a valve and gasket also. Sorry I have no idea how to replace this though. $200+ cost or somewhere around there from the local Chevy dealer.
