My CEL came on last nite. After looking around a bit I noticed 2 vacume inlets that are not sealed and no line going to it... Just wide open. What should I do here?

 

Those are not vacuum inlets. That's the throttle body coolant input/output.

Do you have the SES Code?

 

If its what i think it is, it's where coolant gets pumped into the intake to help get the car up to temperature faster for the sake of smog.

Most of the time when you install a turbo/supercharger you by pass that line.

As far as the check engine light goes.... you are FI-ed go check the code My guess is its a misfire or too rich code.

 

Those are not vacuum lines, they for the water lines to the throttle body, which appear to have been bypassed at some point.

I wouldn't worry about it.

 

I believe those are the TB heater lines not vacuum. Looks like yours is bypassed in bottom picture with little yellow male-male coupler. So your problem isn't there.

 

No code yet. I'm going to have to take it to my guy down the street tomorrow to get that.

Btw what do you guys recommend getting to retrieve codes? So I dont have to drive to my buddy's shop all the time.

roger that.... they are cheaper than I expected.

Question: I hooked up fuel tubing to those 2 exposed ends just to see what's happening and was getting a small amount of vacume. Should I seal them up?

Question: If I drill out the pcv valve, airflow will travel in both directions. Passenger side I have a catch can and would like to open crankcase vent by drilling out the pcv valve. But when i'm boosting won't that vacume inlet at the front of the manifold turn into a positive pressure? Dont know if I should drill it out if boost is going to travel back in the wrong direction.

 

those exposed ends have nothing to do with vacuum as people have said. It does not matter 1 bit if you put hose on them.

if you drill out your PCV, then you have to put another check valve in (basically another PCV valve) is you leave it attached to a vacuum source that can see boost (IE anything behind the TB)
