07' CTS 2.8 Misfire
Hey Everyone,
Hope you guys can help on this one. The engine started with a cyl 3 misfire. I pulled the plugs and took a look and the gap was .74+ on most and only one cyl had minor oil. Worked through the painful process of replacing all the plugs which came factory at .5. After replacing the plugs I now have a cyl 5 misfire. It idles rough but runs fine for all other driving. Any help would be greatly appreciated.
Edit: Forgot to mention this is a car that was driven by mother in-law for around the town runs w/ 70k miles.
Thanks!
