Is there a need to use fully synthetic oil to solve this problem? Also noticed that the engine vibrates more when idling than before. Just got my oil changed 2 months ago with mineral oil. Does the egr valve and boost sensors require immediate attention? Where can I find those? Im having a hard time identifying which is which. You think air ducts are clogged? Tnx in advance
have the same problem?
