I have a 93 960 that i paid $1 for (long story short, it had over heated after having blown a hose and i was told it kept over heating after that and the people were told they needed a new engine, almost 5000 miles later i haven't really had any issues with it and have been doing work on it like changing the timing belt).

Anyway i think i need to replace the vacuum servo or i have a vacuum leak and i am wondering if i do indeed need the servo, if anyone knows where i can get it and how much it might cost me? A mechanic told me it's probably not the servo as those usually don't go bad. Can anyone help me with this?

One other unrelated question is this car has a moonroof in it (sun roof with glass) which from what i can tell is not a factory option and might be a 3rd party thing. The thing is it now has some play in it and it doesn't want to close with out me holding down this little wind deflector that pops up when you open it. Anyone have any insight on this?
