vacuum leak on 92 325is, i need help!!

vacuum leak is driving me nuts!! need help plz

--------------------------------------------------------------------------------

Hey guys, need some help here as im at the end of my wits, i have a '92 325is, with a serious vacuum leak as far as i can tell, causing the idle to move anywere from 600rpm to about 1400rpm. whats i cant figure out is the leak is intermittent sometimes idles alright, with only slight variation (between 100 rpm) soemtimes terrible (changing by 500- 1000rpm) all the hoses appear to be okay and its as if i can here it sucking in major air somewhere underneath the intake manifold, or throttle body plate, i was thinking possibly idle control valve, but i dont have enough experience or the money to just start swapping out parts, has anyone experienced a problem like this? your advice would be much appreciated!

thanks guys,



Sean Thompson

Ive been there, had it checked but did not find the cause.
How does your car run on the highway and acceleration? Is it still mean or do you feel it slop out and stutter? (JW b/c my car sometimes slops out, while other times it feels like its at peak performance).

i had a similar problem and found that my PCV valve had cracked and was causing a leak. It's only like 5 bux from the dealer, although I had to get one ordered because they didnt have it in stock. Check that out before moving on to more expensive stuff.

oxygen sensor can cause idle to fluxuate a bit.
