pretty sure my IAC is bad on my 94 540i, already cleaned it,no change. with it plugged in the idle goes up and down and sounds like a huge vac leak, with it unplugged it idles smooth and no vac leak sound.
just replaced the t-body gasket, intake gaskets CCV and gaskets, plugs and vale cover gaskets.
can i use a IAC valve from a e39 540i?
