My check engine light has been on for a month now I ran a diagnostic on it and got a code that told me engine was running to lean. I replaced fuel filter, pcv valve and all oxygen censors have previously been replaced under warrenty. Im getting a blue grey smoke coming out from behind engine. Last oil change I did I realized that there is a oil leak seems to be coming from a tube behind the engine, not for sure though. Any advise on this would be great I am really stumped at this point.

Do this first check your pcv valve to see if it is clogged if so replace it. Then get back to me
