I have a 2008 C6 coupe with a cat back Corsa exhaust. Recently upon startup every time I use it. It seems to run very rough, almost like it’s running on 4-6 cylinders. I currently have 35,000 miles and all
regular maintenance has been performed. BTW it runs well after warmup.
Any thoughts on what to check?

Thanks I’ll look at that tomorrow. Also while putting it away, low air pressure in the right front tire. I have to check it out to
too.
bring the tire up to the recommended pressure and watch it. See how fast you lose lbs. If its slow you have a nail thats still plugging the hole...if its fast you have a puncture. Whole big controversy on how to repair that...lol....depending on your particular usage
I had a rough Idle that was always there, so I put on a new set of wires and that cleared up about 70% of the roughness. Next I've bit the bullet and have a new set of injectors for the LS2.
Rough idle/start
