Lefty205 Posted February 11, 2020 Share Posted February 11, 2020 Periodically my 2016 MKX will very strongly smell of raw gas right after starting, backing out of the garage & continuing for a time after driving away. The dealer has been unable to identify the cause, although by "tightening things up" in the engine compartment it will be ok for a while. Does this sound familiar? Has the cause been found? Great car other than this annoyance! Quote Link to comment Share on other sites More sharing options...
YT90SC Posted February 11, 2020 Share Posted February 11, 2020 You're smelling it in the cabin? Several possibilities to check, In order. Check for missing/broken hardware on exhaust manifolds, cats, or Y pipe. Check manifolds for cracks. Soot around any pre-cat connection is also an indicator of leakage. Loose spark plugs. Fuel leaks from rail/injectors and EVAP system. Check for missing/damaged grommets, air vents and decklid seal, just as they would for CO issues in Explorer. Make sure HVAC is at latest software level- won't solve issue, but may mitigate it some. Quote Link to comment Share on other sites More sharing options...
