Where does this go? Everything else is already plugged in. Is it supposed to be capped?

Hi,

Just looking at it, it's hard to tell. Do me a favor. First, start the engine and place your finger over the end of the connector to determine if there is vacuum present.

Next, at idle, have you noticed any vibrations or a rough idle?

I attached a pic below showing the vacuum hoses I suspect it could be related to. I highlighted them. If possible, take a pic further away from the engine so I can see more. Also, see if you can follow that hose to determine where the opposite end is.

Let me know.

Take care,

Joe

Hi, just to jump in. Start your vehicle up and turn the A/C on. Can you adjust the direction of the airflow? If it is blowing on defrost then that hose needs to attach to the intake manifold. If the air flow corresponds to the vent settings, then check to see if the EGR valve is missing the hose. Let us know.

If the vacuum line is for the HVAC unit, as long as the fan motor comes on you should still be able to change. The direction of the airflow if it is vacuum operated. If it is stuck at defrost when you try selecting a different setting, then that hose is for the HVAC unit. Let us know if the air flow is stuck in defrost, please.

Hi,

Is this the engine you overhauled? Also, is there a vacuum to the hose in question? I'm trying to determine if it goes to the intake or a component.

Let me know.

Take care,

Joe
