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.

Can you clean the EGR valve on a 1995 Pontiac Grand Am?
You can clean the EGR. No promise it will work. I have an idle problem on my `97 Grand Am Se. Shop told me I could clean it and it might solve my problem. Just remove the EGR with the 2 bolts from the top of the manifold if you have a 3.1 v6 like I do. Then leave it upside down with throttle body cleaner in it. Fill the EGR level with cleaner and let it soak for at least 30 min or more. Then reinstall. This will remove any carbon on the inside which plugs the needle from pushing out at highway speeds. Hope this helps. If the problem returns in a week or so then replace with new EGR. New EGR is about $200-300! Cleaning seems to have helped my car did that about 3 weeks ago.

The vacuum hoses from the differential pressure feedback EGR sensor typically connect to the EGR valve and the intake manifold. One hose usually routes to the EGR valve to monitor the pressure difference, while the other connects to the intake manifold to measure the vacuum level. It's essential to ensure the hoses are connected properly to maintain accurate sensor readings and proper EGR operation. Always refer to your vehicle's service manual for specific routing details.
Where is the egr valve located on a 1996 mazda mx6 2.5 l v6?

It is connected to the exhaust system and has vacuum hoses attached to it. To access it, you may need to remove some components for better visibility and clearance. Always consult a repair manual for specific instructions and diagrams for your vehicle.
What causes black smoke from the exhaust?
Black smoke from the exhaust typically indicates an excessive amount of fuel being burned in the engine. This can be caused by a variety of issues, such as a malfunctioning fuel injector, a clogged air filter, or a faulty sensor that affects the air-fuel mixture. Additionally, it can occur in diesel engines when there is insufficient air for combustion or if the engine is under heavy load. Proper maintenance and diagnostics are essential to identify and resolve the underlying problem.
