SOURCE: bad egr valve

the egr valve is located at the end of an exhaust supply pipe (1/2" diameter) from the exhaust manifold. there is also a sticker under the hood that shows this location, it is the emissions sticker.

SOURCE: 2004 duramax black smoke and sputtering when

Black smoke means "fuel not being combusted" or "runnig rich". I have no doubt you have gasoline. Your spark may not be burning the gas. Is there a check eng lite? If EGR was sticking, you would probably get a check engine light for this. If your truck has a Vortec design, I would find out if you need a new "spider". What is your mileage? Are you due for a tune up? What spark plugs are you using? Vortec? "Not all the time" sounds like intermittent. When was the last time you changed the fuel filter? Can't hurt to change this. This would be the actaul starting point for me. I would change the fuel filter which is under the driver under the chasis. You will need a 16MM and a 20MM. USE ONLY LINE WRENCHES. You may need a fuel line disconnect kit too depending on your model. Notice it only happens on acceleration? that is when you are forcing even more fuel thru the system, but not enough of a fuel stream make cause sputtering and when the fuel comes thru too rich that would be the black smoke. It sounds like you have the 2 extremes. is there afuel regulator on your vehicle? If so, you may need to change that too. Good luck.

SOURCE: i need to know how to install a egr valve in a 05

Once you are able to identify the EGR, you simply unbolt the valve and ant other obstaructing part. Clean its surface of carbon. Repalce the gasket if worn. Any sticky bolt/nut that you encounter could be removed by spraying some WD-40 around them. Also disconnect the negative wire of the battery first. Diesel do run hot, so get ready for some hard bolts to loosen.

1994 saturn sl 2 oxygen sensor light came on replaced it. now the code is saying the upstream oxygen sensor input volage above normal operating range???? and theres a bad odor coming from car???


It could be the oxygen sensors but when you said there is a bad odor I would bet that you have a bad EGR valve. It will send a code for the oxygen sensor if there is problems with the EGR valve. A lot of the time the smell is like rotten eggs when you have a bad EGR.

2000 toyota camry v6 code p0402


The egr valve on that motor has a egr positioning sensor mounted on top. The sensor goes bad and the ecu can't determine the how far the valve is opening so it opens it too much. This causes surging of the engine under light throttle application. Also as stated above the egr can stick causing rough idle. Either way if you get the valve from the dealer it will come with the sensor solving both your problems.

Check the EGR tubes for carbon build up. It's not the fact that the EGR valve keeps going bad, the reason that there it thinks it's malfunctioning is the tubes itself will not allow enough flow. Remove them and clean them out the best you can.
