It is on the back of the intake. You cant really see it very well. They run about 120 bucks or so.

wow, so how the heck am i suppose to get to the erg? after looking at it i need to hire a midget mechanic or something juezz. I'm not the smallest dude ever. I did find 2 hoses the were cracked/ lose but that probably would be to easy for my luck, i'll find out soon. Is it more likely the egr valve is causing the code or the vacuum solenoid possibly? I don't want to even attempt removing that valve

any tips?
