RE: EGR
 

Thanks a bunch for the advice...I'll either have to write it down (grandparents have dial-up) or wait till I get home from college to try that stuff.

Also, you got a lot further than I did on that link:D i clicked once, glanced, and closed. I'm not really worried about fixing that stupid valve, but I want my computer to be happy.

RE: EGR
 

EGR valves basically do this by sending some of the exhaust gas through the intake manifold back into the cylinders. Because exhaust gas most often doesn’t burn, it stays and takes up space in the combustion chamber and lowers the temperature there. Older vehicles used to have mechanical engine EGR valves, but the newly manufactured ones have electronic EGR valves.However, the function of EGR valves remains the same, whether they be mechanical or electronic. An EGR system usually doesn’t require regular maintenance, but it should nevertheless be checked so as to ensure that you are always complying with emission standards.

Emissions are so overrated:D I don't think they check for emissions in the county I go to school in. But back home they do.
