a friend said that what is wrong with my 760 turbo 1988 might be because of bad vacuum hoses or there is something that is plastic that has 3 ***** in it that regulates vacuum. I think that this partis called the Vacuum Check Valve. My question is where is it located on my model is someone has a pic that would be most apprecated. thx

 

NO pics but look for a big Valve in the middle of a hose by the engine.It is usually Grey or Black.

 

hey thanks
