Anytime I drive above 75 for a period of 5 or so minutes, the check engine light will come on until I turn off the car and back on. Normally this wouldnt bother me, but at night its this blaring orange light. Any ideas?

http://www.thirdgen.org/newdesign/faq/thirdgen.shtml at the bottom...check to see if you have any stored codes...figure out which ones and diagnose from there.

maybe your EGR valve is carboned up....

I'd guess it is the EGR valve, pull it and clean it and see if it goes away. You may need a new one.

:stupid:
the egr only opens up in cruise situations where there is steady vacuum. so rolling steady on the highway is when the ecm would notice it was not acting right.

Yep happened in my car. I had to pay $100 for a new EGR valve. For some reason, car ran alot better afterwards.

$72 later, new EGR installed. Old one was all carboned up. So far no lights.
