Have a 4g93t gdi in my car lancer but it's running extremely rich wide band reads 9.8 and below, this causes my spark plugs to foul up so I have to change plugs every month, there's no boost leak, did an I jector clean and same issue, is there any way to reduce the fuel going into the engine? Or would a remap of the ecu help?
