What's this go to thread
 
First picture is pass side towards the pcm.
Also what exactly is that harness below my hand, because 2 wires are straight up ripped out.

Second, this is drivers side all the way back of the intake.
Something is deff unplugged, is this from the EGR delete?
Don't remember that before though.

the line you are holding is the vacuum supply line for your hvac controls. there should be a one way check valve somewhere down around that hvac box that runs to the interior of your car. as for the wires you will need to take a picture of them. those connectors go to numerous different systems in the vehicle

1st pic If the other end of that vacuum hose is hooked up at the intake, you have a vacuum leak.

Wiring is C100 or C105.

Once again thanks for your vast knowledge.

That vac line in the first pic runs into that harness that's below my hand, not the intake from what i saw, but looking at the wiring harness diagram you provided looks like it should connected towards the back and that runs into the intake?

And what is my 2nd picture / is it needed to be plugged in? Looks like the EGR right? Which i don't have.

it goes to the charcoal canister purge. it is not "required" but it might be by law in your area and is one of those things more people will tell you to keep than to delete.

The second one is to the EGR solenoid-not EVAP. If you don't have the EGR stuff, it's kinda hard to plug it in, eh? If EGR is programmed out, there should be no issue.

Yes, the vacuum line goes into the wiring harness and comes out at the intake.

Thanks everyone. Hopefully this is why my
Idle has been fishy lately.

Okay part 2, making sure I have this right.
The first picture is two ends of a vac line i believe. The one towards the back runs into the wire harness and i assume into the intake. This is what i need to connect to the other vac line pictured to resolve the vac leak? If so i'll need a new fitting because they don't go together, that's why i'm slightly confused.

The connector(s) pictured in 1 & 2 I believe are the A/c compressor and pressure senors? The car doesn't have AC so that would make sense :)

You must not have looked at the picture link I posted. You are missing the vacuum check valve. That is what those connect to. Three hoses connect to it.

:emb:
just one of those weeks i'd probably forget how to ride my bicycle if i got on it. Thanks. Only $14 on amazon i can live with that.
