  • Vacuum diagram for EFI Festiva anyone?

    I'm sure it's not posted online for a reason, copyright and all that, but can someone "guide" me here? Here's what happened...

    I just got this car and after driving it for a few days, I think my heater core is clogged. I hear that death gurgle inside the dash every once in a while but my temp gauge doesn't seem to move so I'm like, "let's just bypass the heater core for now since the weather is nice and figure out the gauge after that." I go to the parts store and they give me 5/8" heater hose for free, thanks! But after test fitting the hose around the intake manifold, the Festiva doesn't seem to want to idle on the way home. The only way I keep it running is by keeping on the throttle. I stop at the nearest gas station and look around and at the intake manifold, and low and behold, there appears to be a vacuum leak from an unknown vacuum port. I plug it with my finger and the car idles fine so I plug it with some tape to get home.

    Long story short, what is this supposed to connect to:

    1993 Ford Festiva - SOLD
    1986 Toyota Cressida - #stressida hmmmmmm SOLD!!

    Nothing. It's an auxiliary vacuum port that should have a plug on it.
