ok so i tell the gm dealer to put my hummer back together because i'm not forking out 6000 bucks so they do ..i pick it up it dies in the parking lot ..i start it back up and dies again ..i almost started crying started it back up and started down the highway it started to run a little better....drove 2 miles or so and it never died ...took to my buddies shop he checked the compression every cylinder was running just fine.......called the gm dealer they never ran the hummer after putting the cat converters on the went by the sound of the engine and the dinostic test ...once i ran it for miles it cleared the cylinders out got oil back to #5#7 so long story short my hummer run great and the gm dealer is on my sh!t list

Tell me more about the converters? Did they replace the converters, if so, why did they do that and what did they tell you was the cause of their failure?

did you see if your dealer will help they have the ability to warranty it if not have them call their local service rep and he will probably help in some manner
