I HAVE REPLACED THE EGR VALVE 3 TIMES ON THIS VEHICLE. I AM HAVING TROUBLE WITH THE VEHICLE RUNNING ROUGH. I WAS TOLD I HAVE ALOT OF CARBON BUILDUP AROUND THE EGR PORTS AND THIS IS BREAKING/FLAKING OFF. THE DEALER SAID THEY WOULD HAVE TO TAKE THE CYLINDER HEADS AND INTAKE MANIFOLD GASKET AND SUBMERGE IN A HOT TANK OF ACID TO CLEAN THE CARBON OFF THESE PARTS. THE REPAIR QUOTE WAS $1600.00 AND THERE WAS NO QUARANTEE HOW LONG THIS WOULD TAKE CARE OF THE PROBLEMS I AM HAVING WITH THIS VEHICLE.

I EXPERIENCED "HARD STARTS" "ENGINE RUN ON" AND "ROUGH IDLE" FOR APPROXIMATELY THREE TO FIVE MONTHS. THE PROBLEM WAS DIAGNOSED AS A LEAKING FUEL INJECTOR. THE GM DEALER GARAGE INFORMED ME THAT THEY "SEE THIS ALL THE TIME WITH GM PRODUCTS" AND THAT THE LEAKING FUEL PRESENTED A SIGNIFICANT FIRE HAZARD. THE GARAGE STATED THAT WHILE GM WILL REPAIR FUEL INJECTORS WITH CALIFORNIA EMISSIONS, THEY WILL NOT DO SO WITH FEDERAL EMISSIONS. GM HAS BEEN NO HELP AND TOLD ME I HAD NO RECOURSE TO RECOVER THE MONEY PAID TO REPLACE THE FUEL INJECTOR (APPOXIMATELY $700). IT SEEMS TO ME IF THE PROBLEM IS COMMON, PRESENTS A SAFETY HAZARD, AND HAS BEEN THE SUBJECT OF AN ACKNOWLEDGED PROBLEM, SOME INVESTIGATION INTO THIS ISSUE SHOULD TAKE PLACE..
