Check engine light is on.
I have replaced my DISA valve and also replaced the MAF.
Spark plugs are new, air filter is new, Fuel filter is new.
I am getting code P0175 Bank 1 System too lean
P0172 Bank 1 System too lean.
Any cluese what is causing these codes?
As noted before smoke test is the best way to determine a leak that is producing a lean code.
