yeah, ordered a coild pack from Rockauto to replace the front 4 coils. I used one of the four to replace the bad one in the back and the misfire stopped.....
Still have crap gas milage but until I replace the exhaust, thank you GM for an all or nothing exhaust... I'll continue to have the low gas milage....
