Hey everyone! I am new to this forum, so sorry for any inconvenience. My 1999 C230 Kompressor Sport was stalling, getting decreased gas mileage, etc... so I decided to explorethe threads on this forum and I discovered that there is a problem with my Mass air flow sensor. I found a cheap replacement online for about 100 dollars, and now I need instructions on how I would go about replacing the old one in my car. Thanks so much!! I understand that it is a simple process, I just have no idea where the sensor is or how to replace it.
