Where does the EGR vacuum line go to?
The vacuum hose on the EGR valve goes to the EVR (EGR Vacuum Regulator) solenoid which should be located on the rear face of the left (passenger) strut tower, above the TAB and TAD solenoids. EGR is not functonal when the engine is cold, or at idle, or at WOT.
Where does the vacuum hose connect to the engine?
The easiest way to find were your brake booster vacuum line connects to the engine is to trace the vacuum lines from the brake booster to the engine. The vacuum line is usually connected to the upper intake near the back or either side of the intake.
What is the purpose of a vacuum hose?
A vacuum hose, which can also be referred to as a “line” or a “tube,” is a flexible rubber connection that routes manifold vacuum to various components and accessories. Since vacuum can be used to power everything from a vacuum brake booster to a windshield wiper motor, a vehicle may contain dozens of these hoses.

How do I know if my EGR valve is stuck open?
Symptoms of an EGR valve that is stuck open include rough unstable idle and stalling. Often a car stalls when stopping after exiting the highway. If the EGR system is clogged up, or the valve is stuck closed, the combustion temperature increases.
What are the symptoms of a vacuum leak in a car?
Here are four signs that your vehicle has a vacuum leak.
- Sporadic Idling. A vacuum leak introduces excess air into the engine, and this directly affects how your engine runs.
- Engine Hesitation. Your engine trouble will not be limited to your idling if you have a leak.
- Vacuum Sounds.
- 4 Check Engine Warning.
Do you need to replace the EGR pipe?
Even though the functioning of the EGR system may seem complicated, replacing the EGR pipe won’t be. You may need to remove various air intake parts to get at the EGR hose Then you’ll need to unbolt the EGR tube from the exhaust manifold and separate it from the EGR valve, unbolting it and disconnecting the associated vacuum hoses.
What causes a gas leak in the EGR tube?
The EGR tube can become clogged over time. The exhaust flowing through it can leave behind residue that builds up in the tube. The high heat of these gasses may also damage the tube, causing leaks.
How does the exhaust gas recirculation ( EGR ) system work?
The Exhaust Gas Recirculation (EGR) system takes a small amount of exhaust gas from the exhaust manifold and pushes it into the intake manifold to help reduce nitrous oxide emissions.
