GDI Carbon Cleaning on a 2016 GMC 3 6L that had a Hesitation and Slight Misfire with only 22K on the engine. Performed a ATS Chemical GDI cleaning and the problem is gone. The process is so simple that I thought I make a video to help some of my student/shop owner with using this great GDI equipment and chemical cleaner. When it comes to GDI cleaning this is the only way to go.
