Code P0400

I got a check engine light in my 96 1.3. It says it is a P0400. Autozone said that was an EGR valve...is that what it is and if I do not replace it will it reduce the gas mileage or mess up anything else?

Thanks,
Jeff

:attention

I got the same code on the same car.

Yeah but yours look a lot sweeter than mine!!! What wheels are on your Metro :thumbsup:...Back to the problem, did you get it fixed or did it cause any other problems?
Thanks,
Jeff

My wheels are Borbet type H(I think).I never fixed mine and it doesn't seem to affect anything.
