This is probably a stupid question but I'm having a big problem with my vacuum on my car listed above., My buddy thought he could do my vacuum and really messed
It up and I have tried to put it back with no success, I've looked at sticker on the car and it's not matching what's on the car close but not the same. Motors stock I don't know. Can you help me?

Hello, so you just need a vacuum hose routing diagram for the engine. Has the engine been swapped out in this vehicle that you know of? Hopefully the diagram in service info is not the same as what's on the car. I'll post it here in a minute, and if you have any questions, we can try to give you some direction. Can you take a picture of the top of the engine and post it here so we can see what you are dealing with?

This is the diagram for the EGR valve, with its vacuum solenoid, since this is a bit of different type of setup. It has a vacuum switch (VAC SW) to monitor the EGR solenoids operation.

Okay, let's try again with my car. My buddy really messed up the vacuum on my car thinking he was doing me a favor. Anyway, I have to redo all the vacuum lines on my car listed above 2.8. I look at the sticker under the hood and it is a little different. The 2 big lines coming out of the canister one goes to the EGR, and the second one goes where to fuel tank right, but it has a hose going off it towards the intake that where I'm confused, I try to send a photo, but my phone won't do it. Can you help?
