Hi to all. New to this forum and looking for some guidance. I have a 2008 Yukon Denali. Running fine then within a minute while drivIng it went from a little rough to an extremely bad misfire. Really popping through the exhaust. I had to pull into a parking lot and shut her off. Barely made it into the parking lot! The check engine light did not come on which is throwing me off as to where to start troubleshooting. I would think the check engine light would have came on if it was a bad coil, clogged cat, maf but nothing. Any ideas? Should I put my scanner on it anyway? It would be greatly appreciated. Thank you!
