first off I would check the brake system because you dont want that to go bad
you might have to take the calipers off and check the boots,
area's to check is around master cylinder, calipor's, wheel cylinder's if you have drums, brake hoses and lines and bootsers and sometimes abs systems... if your not feeling that good about checking them and taking the system aprt and checking each one... you might have to take it to a shop...
FYI...now over time with you brakes getting thinner you will drop a little bit of fluid because its taking more space to close the brakes... but not much loss
never allow the master cylinder to go empty!!! you will have to purge and and purge the whole line and everything very tuff to do with out a pro system

what was the codes???
where they lean or rich??

Your caps blew my eyeballs out and I couldn't read the entire thread, but if you replace the EGR valve, I'm 80% sure your problems will disappear. I think RockAuto has an ACDelco for your gen for under $30 and you could easily replace it yourself. Good luck.
