it will... not too much symptoms but it'll do feel some kind of less responsive, due to the lower gas quality, remember that octanage determines the resistance of a fuel to burn, so the more octanage, the easiest is to burn it
lincoln navigator
hellow just wonderin if you guys know where would be the heater core on my 2003 Lincoln navigator
Not using premium fuel caused that in my 2004 Navigator.
That would depend on the year of your Navigator and Expedition. See the related link.
I would say NO ( I was looking at the 2001 Lincoln Navigator Owner Guide and it does not show anything about it having a cabin air filter )
On a Lincoln Navigator : Bank 2 is the drivers side of the engine * sensor 1 would be close to the engine BEFORE the exhaust enters the catalytic converter
I would think that the most luxurious car is the Lincoln Navigator.
It could be one of your vaccum lines that collapsed
These are completely electronic. You may have a loose wire.
I would check your alternator*(check the spelling).
I'm not a mechanic / technician but I know the engine cylinder locations are numbered : firewall 4 - 8 3 - 7 2 - 6 1 - 5 front of Lincoln Navigator so I assume the coils would be : firewall D - H C - G B - F A - E front of Lincoln Navigator
You can of course but it will provide you no benefit whatsoever. You will get no better mileage, have no more power, and may even experience hard starting. It would be a total waste of your money. Use exactly the octane that Lincoln recommends. It is a myth that a higher octane fuel helps any engine that is not designed for that higher octane.
