Default Re: P0404 that fails to respond to changing the EGR...

I don't have any of those symptoms as related on those documents. So that seems like a good thing.

Have plenty of power during acceleration, no hesitation, no overheating, no engine stalls. Even after it warms up. No noticeable issues when the A/C is turned on either.

Also starts fine in just a crank or two. Has great fuel mileage.

It's just that the P0404 SES light comes on after 30 miles or so after I've reset it. But I can drive for weeks with no other symptoms.

Thanks for your input.
