C7 GS Engine Backfire ???
I have a 2017 C7 GS Automatic with 17k miles on it. Today I was driving about 20 mph and gunned the gas real hard to accelerate and the car backfired on acceleration. What the h***. I always run the super unleaded pump fuel, 93Oct. That has never happened to me before and I hard accelerate often, but usually off the line. Has anyone ever experienced a backfire on acceleration like that and what would be the cause?? The car was warmed up and the outside temp was about 60 deg. I had been driving it for about 30 minutes beforehand. Any input would be helpful. Thanks

Not yet…but it’s not a daily driver so when it is driven it’s not in the mornings when anyone would be sleeping. Plus with the NPP exhaust I am able to put it in stealth mode and it sounds like a stock exhaust until I get out of my neighborhood. Then all hell breaks loose when I open the valves back up.
