Will a car get better gas mileage if the EGR valve is blocked off?

Not really. The EGR valve allows the computer to send far less fuel when the vehicle isn't running hard. If a vehicle doesn't have a functioning EGR valve, then the fuel mixture is cut, you'll burn valves and possibly pistons. Engines that run too lean WITHOUT a functioning EGR valve don't have much of a life expectancy. It's not a good idea, but then, there are plenty of people out there who don't have a clue what they're talking about who will tell you otherwise. If you have a question on the subject, talk to a dealership mechanic or somebody who works on them full time.

Does the egr valve have anything to do with the gas mileage?
A malfunctioning EGR valve can definitely lower fuel economy.
Can you block egr valve off on a terrano?
Blocking off an EGR valve can make the car run rough. The fuel mileage can suffer as well, since the car is designed to have the EGR valve operable.
P0401 egr insufficient flow replaced oxy sensor runs 300 miles ck eng lite on 96 acura tl?
If you have an egr valve failure why are you replacing th oxygen sensor? Most likely the EGR valve assembly is blocked or partially blocked. Often they build up exhaust deposits on the EGR valve and ports.
How do you fix a code P0401 Suzuki 07?
Remove EGR valve and inspect for blocked or restricted passages.
Where is the egr valve located on an h22a4?
The EGR valve is located at the front of the h22a4 engine. The EGR valve is right beside of the front of the EGR valve.
If you have changed your egr valve and deleted the code and it still reads p0401 egr valve insuffasante flow what do you do now?
You also need to clean the "passages". EGR valve puts exhaust gas back into the engine intake under less than full power situations. When that happens exhaust deposits build up on the walls of the passages. Replacing the EGR valve was only half the repair, you also need to clean it out. There is a tube from under the EGR valve to the exhaust manifold. That is probably blocked.
Can an egr valve cause a car not to start?
No Egr (exhaust gas recirculation ) is to help better fuel economy
Why does the engine light keep coming on indicating EGR valve in a 2000 Mazda Protege after the EGR valve and the EGR booster sensor were replaced?
Either there is no Voltage or Vacume going 2 the Valve OR the Passagway under the Valve is Blocked. Clean the EGR Line with carb cleaner to ensure not any blockage. If you are referring to the check engine light and are still receiving a code indicating EGR valve, then the problem is that the EGR valve is being effected by the problem. The EGR valve is not the problem, it is just the component that is being effected. Code readers only tell you the effected part, not necessarily the bad part. This is one of the big problems with autozone's free diagnostics, you get what you pay for.
Can you bypass the egr valve 0n a 94 5.7 350?
You can bypss the EGR by putting a bolt in the vaccum line going to the EGR valve blocking the EGR solenoid or alot of people make a plate replacing the valve with a plate but it will set the check engine light its better to just fix it.
Where is the EGR valve on 95 Honda Del Sol?
There is no egr valve on a 95 Honda del sol. I looked all over mine and on the internet, no egr valve. If your emissions are screwed up replace the catalytic converter and have a pro check your timing. Most of the time it is your cat. I am still looking for the answers to bad gas mileage, hard to determine why but many del sols lose that good gas mileage for no apparent reason.
How do you fix egr insufficient flow on a 1997 Camry?
It could be one or more of the following components, EGR valve, EGR regulator, or a VSV (Vacum salonoid valve) which is a bit hard to reach in case you're thinking of DIY. It can also be blocked vacum hoses and carbon deposits in the intake manifold.
Can a bad EGR valve cause high hydrocarbons?
Yes, the EGR valve, or port EGR
