I agree with HMAC300. The EGR will not cause a misfire.

Sorry to hijack the post but my 2000 blazer with the 4.3 is getting horrible mileage, between 8 & 10 mpg no matter if in town or on the highway. I changed the air filter, plugs and wires and little to no change. I don't know the history of it so no idea what had been done. I do know the 4wd doesn't work and it is missing the vaccum line that goes to the actuator, but haven't had time to dig farther on that yet. I have read the EGR valve can get plugged and hurt the mileage and that it can be cleaned rather than replaced. Is that true? Or am I better off just replacing it? What else could be causing my poor mileage? I hate sticking a lot of money into it but it's in great shape so may have to bite the bullet.

Hey LITTLEE_DOMN8R,

Is the engine running okay? If so the the EGR valve is okay. I would look more toward the injector regulator leaking internally which is inside the intake manifold.

Please let us know what you find so it will help others.

Best, Ken

Where is the EGR valve located on the 2.2 liter four cylinder Vortec engine?

Hello,

The EGR valve is located at the rear of the engine on the 4 cylinder and at the front of the engine for the 6 cylinder.

Here is a video on how to test the EGR valve check it out.

Here are the location diagrams (below).

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken
