    Re: Ignition

    If you are checking for vacuum leaks, you might as well check the idle signal of the throttle position sensor. You do not have to remove it to test if it sort of works. Connect a multimeter to the middle and idle pin, and have it test for resistance. It should switch between open and closed when you slightly move the throttle.
