Random vacuum question.

[Myco]

If you pull the vacuum from your fuel pressure regulators and then pull the vacuum from your EGR should the vacuum between the two be about the same?

 

[DLF]

Not likely, the vacuum at the FPR is constant, the vacuum at the EGR valve is switched.

 

[Myco]

Switched meaning on/off? So if there is vacuum should it be a vacuum of the same consistency of the FPR's?

I'm asking because under idle the vacuum for my EGR is about 1/2as much as the FPR's.

How is the EGR switched? Could you explain that?

 

[DLF]

There's a solenoid that the PCM uses to control the vacuum to the EGR valve. On a stock Gen 2, it's mounted on the driver's valve cover. At idle there shouldn't be much vacuum at the EGR valve, it's only designed to operate during part-throttle cruise.

This is brand new (meaning within a week). I'm guessing it happened when I bled the brakes last week. What is the thing that it goes too?

This what? When what happened? What thing?

You're going to need to ask better questions to get decent answers.

That pale yellow vacuum line (is it cut?) goes across the front of the motor and down to the AIR valve in front of the crank pulley.

The device in your second picture is the solenoid that controls the vacuum to the AIR valve.

Yes it is cut. I bled the brakes last week and my friend was filling the brake reservoir and he must have moved them when he wiped after he overspilled once.

I patched them up with electrical tape as best I could.
Both of the wires are broken actually the red and the yellow wire.

Sorry, I'll be more specific in the future.

All I know of that thing in front of the pully's is that it's for emissions control.

Will it effect fuel economy, idle or general performance of the car?

They're not wires, they're vacuum lines......

The AIR valve only operates for the first couple of minutes after a cold start.

The vacuum leaks, however, would cause issues. Splice the vacuum lines using either rubber or silicone tubing.

Oh, and keep your friend away from your car if he's going to do that kind of damage.
