#33 Fixing auxiliary air valve and idling problem Mercedes 107 450 SLC, D-JET

In this video I work on the 1975 Mercedes-Benz 450 SLC with engine M117 and Bosch D-jetronic fuel injection. The idling was very rough and uneven, but after taking the air valve apart and cleaning it, the engine ran much better. Also, see my other channel:    / @20e_arhundradets_rav   I don't claim this to be an instructional video. It's just me working on my own car and showing what I did. Many more videos to come as I go along with all my projects. Welcome to SUBSCRIBE if you like my content! I will keep posting videos!
