Thanks guys!!!
Now it's starting to make sense! Yes, I have yellow injectors. I feel a lot better knowing they're the right ones! Now here's my question.....
I have a Chilton repair manual. There is no 3.5 liter or 350 SL/SE/SEL listed in it. Where would I find the tune up specs for it?
My car is a '75 450 SE. Did they not have a 350 in america during the mid '70's? Sorry if that's a dumb question, but I'm pretty new to the MB world and I'm trying to figure out why my car is a 450 yet has a 350 engine.
Thanks again for the help!
