vacuum leak???

[pwrliftin]

So theres a ton of vacuum lines in my 86 2.5 5 spd, are there any common ones i should check for leaks? theres so many i don't even know where to start

start with a propane torch (not lit of course). just turn it on and follow each one around the engine bay. when the engine idle speed changes, you've found a leak. :D

 

Oh, and I'd begin with the line that heads into the vacuum reservoir in the front bumper.
