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

yea i already replaced it....

now lets check the egr valve to make sure its not stuck closed. and test to make sure its not faulty. then were gonna go to injectors. have them noid tested. to make sure they are all firing correctly

fuel pressure regulator should be checked also
