    iddle issue

    Hi, The problem is that after taking apart everything to get to the manifold to take it off ,I ended up not removing it so put everything back together for some reason the car doesn't idle properly and dies ,any ideas where to start should I scan with OB11 scanner ,would that show anything .Thanks Alex

    Better tell you that the manifold was loosened but did not take completely off ,just tightened up nuts with old gasket,,, would I have had to replace it. Thanks ,,,,,,, Gasket that is

    Spray around with carb cleaner to find a vacuum leak.

    The car needs to relearn how to idle the car after an ECU reset (disconnected battery).

    My car almost stalls but not quite.

    I takes about 100 miles of driving for the ECU to relearn how to idle the car.

    It takes different amounts of time for each car depending on how far it's drifted from original factory specifications.

    It doesn't show the torque in-lbs for the intake manifold,I'm somewhat baffled,I think 16 in-lbf may be low for it.So I'm thinking that I'll'tighten it as much as I think it should be . If you look at the air ntake black piece it says 80in-lbf I would think that the Mani would be more than that Thanks

    You just multiply the 16 foot pounds by 12 to get inch pounds.

    So 192 inch pounds.

    It's all in foot pounds unless otherwise noted.

    The "80" is Kg/cm or 69.5 - 95.4 inch pounds.

    If your talking about the fresh air duct (part #1), it's a plastic piece so you don't want too much torque or you would squash the plastic.

    So about 80 inch/pounds is about right.
