Silicone spray lube. When it dries there won't be any oily residue left over to attract dirt like would occur if you used WD40.

SOURCE: Difficulty to replace EGR valve in 1999 totyota camry 4-cyl automatic

If you have small hands it can be easy. The space between firewall and EGR is tight but it wasn't too difficult to remove. The vacuum hose at the bottom was hard to pull off and I ended up cracking it and had to splice it. It was more difficult to re-install the EGR then remove it. I had a difficult time with keeping the gasket aligned while bolting it in to the lower tube. I took a few attempts. I suggest when replacing the EGR leave the mounting bolts loose so you can more easily align the metal tube. I would tighten the metal tube at the bottom of EGR first then tighten the upper two mounting bolts on top. It took me about 5 minutes to remove and 15 minutes to replace. I would be sure to clean the IAC too after cleaning the EGR. I sprayed throttle bottle cleaner down the bottom hole located on the throttle body and let soak about 15 minutes then start and run the engine a minute and repeat the process. This helped smooth the idle while stopped at a light. It also stopped the idle from shaking and almost stalling the car out at a traffic stop when the engine was warm.

SOURCE: no vacuum to egr valve

there is an EGR vacuum solenoid somwhere that controls on/off vacuum to actuate the valve. i am not to sure of the location, but follow the vacuum line back from the egr until you find a device that looks like an electrical check valve for vacuum. that is a possibilty. but then again i am a ford,chrysler guy and am just giving you an answer based on my understanding of the functuality of a vacuum egr system

SOURCE: egr valve is bad on my 1989 chevy with 305

You block it off before the valve on the metal pipe that runs to the EGR valve. The problem is that when you go to get it smogged you have to replace the EGR or it will not pass smog

SOURCE: 99 ford expedition 4.6 misses / egr? vacuum?

it's getting to much egr the egr has gone bad and needs replaced.
the diaphragm in the egr is leaking, and default position for air is defrost.so when you hit 3000 rpm you don't have enough vacuum.

SOURCE: EGR Solenoid creates no vacuum

The EGR solenoid is located towards the rear of the car from the EGR vavle and slightly towards the center. It kind of stands on end. There is a vacuum line coming out the top (port C) and a green 2 wire connector plugged into it. Hope this helps.

Where is the egr valve on a citizen c5


  • First you want to open up the hood of your car
  • Find the engine diagram sticker on the inside of the open hood and identify the mechanism that is labeled "EGR Solenoid" on the sticker.
  • Find the "vacuum line" on the sticker diagram and identify its color. This is the line that runs from the EGR solenoid to the EGR valve.
  • Locate the vacuum line inside the engine compartment of the vehicle toward the front of the driver's side. The vacuum line will be the same color on the vehicle as it is on the diagram.
  • Follow the vacuum line from the front of the vehicle where it connects to the EGR solenoid through the conduit that carries it to the EGR valve at the rear of the engine compartment. The easiest way is to track the uniquely colored vacuum line along the path between its two connection points. The vacuum line connects to the EGR valve, which is the disk-shaped object located at the rear of the engine compartment
    on the driver's side.

I NEED TO REMOVE THE EGR VALVE


The Exhaust Gas Recirculation valve does just what the name implies: it diverts some exhau st gases back into the intake system at low engine speeds. This lowers combustion temperature to reduce NOx levels. It also reduces throttle response and bottom-end power.
Disabling the EGR valve is easy. Locate the valve and the EGR vacuum modulator valve (two gold-colored metal stampings, usually at the rear of the engine). The EGR valve has steel lines leading to it from the exhaust manifold. The EGR vacuum modulator has two vacuum lines between it and the intake manifold and a third vacuum (soft) line between the modulator and the EGR valve itself.
EGR Vacuum Modulator
EGR valve (arrow) is shown adjacent tosimilar EGR vacuum modulator valve. EGR valve is connected to exhaust manifold with steel lines. Modulator has vacuum lines only.
Disconnect the vacuum line between the valve and modulator and place any solid object of appropriate size (dowel, etc.) in the line, then reconnect the line. Or you can get a EGR block off plate

Soot in tailpipe, bucks and chokes when accelerating.


Dont know what year or what engine you have. But, if you have an EGR valve(Exhaust Gas Recirculation Valve), find it and unplug the vacuum line from it. Then plug the vacuum line with something like a golf ball tee or of equivalent size, and then drive the car. If this fixes it then you will need either a new EGR valve or a new vacuum supply solenoid which supplies the vacuum to the valve. I hope this info helps.

Just replaced EGR hose & valve copver gaskets on 2002 Ford Escape 4WD. Did test drive, runs really rough & almost stops & cuts off. Any ideas?


OK, if you replaced the EGR hose, did you go all the way to change the EGR Valve? A stuck open EGR Valve can cause a rough idle and almost make it cut off.
Also, a vacuum leak on the EGR valve can cause a rough idle.

prev.gif next.gif Exhaust Gas Recirculation (EGR) Valve Removal & Installation 2.0L Zetec Engine NOTE: When the EGR tube is disconnected from the EGR valve, it must be discarded and a new EGR tube must be installed. The aluminum threads on the EGR valve must be inspected, and a new EGR valve installed if the threads are damaged.
To Remove:
  1. Disconnect the negative battery cable.
  2. Remove and discard the exhaust manifold-to-EGR tube. Use the following as a guide:
  3. Raise and safely support the vehicle
  4. Remove the splash shield
  5. Disconnect the EGR tube fitting
  6. Lower the vehicle
  7. Remove the air cleaner outlet pipe
  8. Disconnect the EGR tube from the EGR valve.
  9. Detach the vacuum line and remove the two retainer bolts.
NOTE: The EGR valve sealing surfaces are soft metals and easily damaged.
To Install:
  1. Installation is a reverse of the removal process. Carefully clean all sealing surfaces and install a new EGR valve gasket.
  2. Install a new EGR valve tube.

Intermittently won't hold idle and stalls


The symptom you describe can be caused by either a bad or dirty EGR vavle or a broken / defective vacuum line.

Try this
1. disconnect and plug off the EGR vacuum supply line

2. Connect a vacuum hose of equal size to the EGR valve.

3. Start vehicle

4. draw a vacuum on the line orally.

a. the engine should die or run really bad.

5. Restart vehicle and repeat checking for same result.

6. If EGR valve is performing correctly as stated in steps 4 and 5 thern you most likely have a bad / cracked / damaged vacuum line somewhere.

7. Reconnect original vacuum line to the EGR Valve

8. Locate source of Vacuum leak.

Check engine light on when check it insufficent EGR valve


yes the passages can be cleaned. They pass exhaust gas into the intake maniflod for reburning.

It could be the DPFE that controls the EGR too. Diff. Pressure Feedback EGR.

there is also a vacuum regulator valve and a solenoid too.

Please rate as fixya if this helps.
