    hi guys finally got round to fitting a FMIC was pretty straight forward but got a cheap ebay jobby and was a nightmare with the drivers side blah blah blah, finally got everything back together started it up and on idle i have a vac of -0.6 bar (-9ish) after a few seconds it drops to -0.7 but i used to sit on 0.8/9 is this just down to the extra length of pipe work etc or do i have a leek in the pipping?

    Thanks
    Tim

    You should always check for leaks after working on the intake system.
    but those readings seem to be ok.

    fmic cannot influence idle vac which is between engine and throttle plate..
    look for a leak off the inlet manifold
