My 2007 Chevy Silverado was starting to almost seem like it was misfiring but I knew it wasn’t rough enough to be a misfire so I put my foot into it when it started to act up and boom I got an engine code and my truck went into limp mode so I was pretty confident what it was after an associate came out and used the scanner tool to read my engine code and boom part was in stock and I was back on the road!.
