Here is a preventative maintenance issue that hardly ever gets mentioned. I think some people believe electronic fuel injectors will last forever. I took an ML320 with 250K and decided to replace the injectors. When starting it had to crank through 5 to 8 compression strokes to fire, so I figured it was overfueling. What a difference after installation. In this 20-minute video, I will walk you through the proper steps to replace the injectors in your M112 or M113 engine. Procedures is the same - you just have two more injectors!
