Great progress!!! I'd say you're well on your way to becoming an expert!

If the injectors for Mercedes are available at a reasonable price I would replace them. You'll find on the internet that you can clean them, I wouldn't waste my time, I ruined a complete set of injectors with the so-called cleaning/testing kit.

With crappy injectors that dribble and leak the car will run but won't be everything it can be. Also if it was spewing clouds of smoke the plugs could be fouled and the car might run a lot better with a fresh set.

Have fun!!

Oh and yes to MFI on the SC - it's a long road to travel but SO worth it in the end!!!!
