3-when i drive my car on 140 KM/h or more , a bad smell similar to a burning oil is come out and it is dissapear as soon as i slow down the speed .. what is the probleem and is it safe and can fire start soon as i ignore the probleem ?

Thanx to be paitent

Yep as said, clean out the breathers and also clean the IACV. Oil smell is more than likely to be the cam cover gaskets so these will need replacing. All these items are covered in the maintainance guides

Thanx for all of u

i went to the maintanice today and the guy there tell me to replace the mass flow sensor since he had clean it before and nothing change

about the smell , he told me that it is normlly hapeend due to enigne hottness which lead to a oil vapour that drops on hot thing and make that smell


and advise or comments plzzzzzzzz

Clean the Idle Air Control valve - very common problem.

Take some of the spark plug leads off the spark plugs and see if there is oil on them. If you have then the hot oil smell is due to leaking cam cover gaskets (also very common).
