In this video I attempt to repair my 2005 GMC Envoy with a rough idle and a weird sound. This Envoy is very similar to the Chevrolet TrialBlazer with the inline 6 cylinder 4.2L Vortec engine. These engines can run for a long time but do have common failures just like any other engine. This video shows me replacing the intake manifold gaskets, replacing the valve cover gaskets and replacing the alternator.
