EGR Systems
When the temperature in the combustion chamber becomes extremely hot, nitrous oxides are formed, which then turn into smog. In order to reduce such occurrence, the exhaust gas recirculation system minimizes the temperature in the combustion chamber.

Why is 2001 tracker failing emissions test?
how many miles are on your tracker
I have a '99 tracker that had very low mileage on it when purchased (used), and it failed emission testing for over a year before I found the problem.Facing the engine with the hood up, look at the left side (right side of car) of the engine and take notice of the wiring harness... There should also be a wiring diagram on the underside of the hood you can follow. the wiring harness in question was short from the factory and with motor rock it had been pulled on and one of the wires broke... I added about two inches of wire to each wire and it passed emissions test without a problem.
I strongly suggest using a soldering gun and heat-shrink wrap.
How do you install an egr valve on a 2001 Chevy silverado 5.3 liter truck?
It's very easy. The EGR valve is located in front of the oil filler neck. All you need to do is remove the electrical wire from the top of the valve, there is a clip on the connector so don't try and pull it off without lifting the clip. Once the wire has been disconnected, just unbolt the two bolts holding the EGR valve on. That's it.

How to change egr valve on a 1999 Saturn?
EGR valves are located on top of the engine near the air intake (the big black hose that comes from the air cleaner box). They usually have a few wires and a couple bolts holding them. With a few tools it's pretty easy. The tough part will be the cost for the replacement.
Where is the PCV Valve on a 98 Pontiac Transport 3400 located?

Where is the EGR valve located on a 1995 Nissan pickup?
You haven't said whether it is an L4 or V-6 engine. On the L4, the EGR valve is located behind and under the aircleaner (throttle body) directly beneath the brass colored bracket closest to the fire wall. The top has a flying saucer look about 4 inches across. It will have 1 vacuum line coming from the top.
Where is the PCV valve in a 1994 Olds Silhouette?
Engine Size? Anyways, look on one of the valve covers, I believe you will find it there.
This depends if it is on a carbureator or on fuel-injection. On a carbureator, locate the idle adjustment screw and turn until idle is satisfactory.
Where is the egr valve on a 1996 Chrysler Intrepid?
Under hood, passenger side, rear engine area, mounted on upper rear of engine
Why is the exhaust spitting out black deposits?
It is important to maintain a car while driving or owning one. When a car's exhaust is spitting out black deposits, it is because there is oil in the system where it does not belong.

Fouled, damaged injectors or incorrect timing on fuel injector pump
Will a knock sensor stop a Nissan Xterra from runing?
no, it would be a problem if you had the supercharged engine in which case you should change it right away. if you have a non supercharged engine do not worry about as it will not affect you. unless you need to pass an emission test.
How do you adjust the Idle on a 1999 Oldsmobile Alero 6cyl?
Computer controlled and not adjustable, if idle is to slow or fast. check and clean the ( IAC ) idle air control valve. this is what controls idling on many of todays cars.
What did the diagnostic code tell you before you replaced the EGR valve? You should not have replaced the EGR valve unless you have already run a diagnostic code otherwise you probably just wasted money.
Oxygen sensors are a more common problem, especially since they routinely wear out. Also, map sensor, throttle position sensor, crankshaft position sensor... and a whole lot more, can cause a check engine light to come on. Don't guess; run a diagnostic code and figure out what the computer is detecting. Then replace ONLY what the computer indicates has failed.
How do you replace an EGR valve on a 2000 Isuzu Rodeo 6cyl 3.2l?
disconnect the wire, unscrew two bolts then you have egr valve in your hand its that easy. ohhh if you are putting new egr valve it's worth putting new gasket.BUT I'll recommend not to buy new egr valve, just clean it.here is the link to egr pic and some reusing detail about egr valve http://www.icess.ucsb.edu/~greg/rodeo/egr.htm
The volume of oil running through the filter while the engine is running. The threads might be the same on the filters but the diameter will most likely not be. This will not create a proper seal if the inapropriate filter is used causing oil leakage and engine ceasing. Please do not try to use a different oil filter than what is recommended by the oil filter manufacturer for the specific vehicle.
Where is and how do you replace the EGR valve on a 1993 Ford Taurus GL V6 3.0?
The EGR valve is the round drum-shaped object mounted on the rear of the intake manifold, to the left of the throttle linkage. It has a vacuum hose coming in on top, and a metal pipe below which leads to the exhaust manifold. To remove the valve, unplug the vacuum hose. Loosen the nut connecting the exhaust pipe to the underside. Remove the two bolts holding the valve to the manifold and the valve should come off. I am about to do the same procedure on my Taurus. I have read that the opening on the inlet manifold can become choked with carbon, so be sure to clean this before replacing the valve.
