My engine light came on so I took it in and the diagnostic machine said "check EGR valve". So I spent $118 dollars on a new valve and had my mechanic put it in for me. My engine light is still on so I took it back and had the machine hooked up again and they said that the EGR valve popped up again as well as a secondary air intake malfunction. What is that? And What do I need to fix it? Where is it located in the engine? I'm getting rather frusterated and would rather not buy parts that I don't need and waste money. Thanks!
