So I recently replace my egr solenoid and egr vavle because I had code P0401. After replacing it by engine light went away. But after that when I drive my car n it get warm my car starts to sound like I have cam but it doesn't. My evo9 is stock. So I was wondering if anybody got any ideas to help me out.
