Excellent advice. I have been planning to check the boost. My first MB was an '81 300SD. On the recommend of a friend I adjusted something in the alda and got more power, Way unscientific, I'm embarrassed to admit it.
I need to study these components and actually understand what's going on. It's not rocket science but it is science, my take anyway.
Speaking of which, anybody know what this item is?
Right front fender, here's a longer view:
My mechanic buddy says it's not getting vacuum, is some sort of toggle. My vacuum is weak, it's far from non-existant, the door locks sort of work as does engine shutoff. I'm ashamed to admit I haven't yet measured vacuum. Was going to do it yesterday but those oil lines kicked my buttocks.
