where would you guys check if you had a vacuum leak that wasnt there all the time? sometimes my car will idle sort of rough to the point where it almost dies but it catches itself. hasnt died yet. i dont know if thats related to a vacuum leak, but other times, the idle is as smooth as can be. usually the former though. i've checked all the connections over and over but i cant find anything. i was thinking maybe a leak somewhere in my IC? thanks
 
it could be ur engine wires that need a tune up. or it can also be your alternator but im not too sure...you should check with a mechanic
 
check the lines to the back of the inlet plenum--part the TB blots to

I had a vaccuum leak b4 and it took me a year to find
it was the piece of rubber hose between the pcv line and the nipple
on the IP had fallen off it was all cracked and stretched out

have you tried spraying all the joints to find leaks?
