Ok so last night on my way home from work. Car ran great until I started to turn a corner and lost all power. Sat on the side of road for a couple hours and finally got the car to start but was missing like crazy. I limped stage car to autozone and hooked the obd2 scanner on it and was getting multi miss reads so I bought new coil packs wires and plugs changed all of them in the parking lot and still no change on miss fire at this point I'm lost this is my first Monty or even first Chevy what do you guys think the problem is..

 

Have your Ignition Module checked. Normally they just stop working and the car just crankes. But it and your computer are the only other links in your ignition system. You could Also have a clogged Cat or a Vacuum leak. All these are worth checking. Hope this helps.
