1997 Dodge Ram 1500 5.9L V8 Magnum
Just fixed an opening in the valve cover (aftermarket covers had four openings, one being unnecessary) and did an oil flush. Now getting multiple misfire code, had an o2 sensor voltage code that hasn't returned, and its been reading C3 4 and 5 misfires. The catalyst system is now reading incomplete when it wasn't before. Where should I begin looking for the source of the misfires? I'm praying for just a vacuum leak, but my gauge is a being a little funny after dropping it. Hoping I'm not gonna need a new cat or o2 sensors. Any advice is helpful. Thank you.
