my check engine light came on and i took it up to auto zone and they checked it and said it was my egr vavle.....now can i do something about it myself or do i have to take it to the dealer??[/quote:017124c4eb]

its easy to replace, but buy it at the dealer, not auto-zone, (auto-zone parts dont last or if they work at all) or buy it from NAPA
