This topic covers a broad range of issues, including anything from a rough-running engine to a failed differential. For that reason, I'm just going to cover the basics of how to go about finding the source of a performance issue rather than pick apart every single system. I also write articles for specific check engine light codes that can be accessed through the ‘Codes’ page on this website. In addition to myself, there are also articles written by other automotive professionals to help you with the specific codes you might have. If available, those can be found by typing your code into the stay dirty search function on the site. We’re adding new articles all the time so check back often.
