I have a 2007 Lincoln Continental with 31,000 miles. When should I change air filter? Thanks

New spark plugs and check the air filter. A new fuel filter is also required every 30,000 miles.

when was the last time it had a tune-up,are the plugs dirty, is the air filter clean,is it carbureted or fuel injected.are the plug wires cracked,how new is the distributor cap& rotor

NOT ENOUGH FULE CHANGE THE FUEL FILTER OR THE PUMP IS GETTING WEAK

Check the vacuum lines going from trans to the intake. Sometimes that will cause it to rev real hi and shift real hard. Even a small leak. They prob jast dropped the pan and changed filter b4. That leaves the oil in the lines there. you have to pump it all out to change it all. My trans in my lincoln just went out. So i would say it wouldnt hurt to change it. Put some lucus trans treatment in it to. Couldnt hurt.

Sometimes by disconnecting the battery will reset the light. After driving 100-500 miles the light will sometime reset after it cycle's which is the mileage it takes for the computer to recognize the problem no longer exist.

check air and fuel filters most likely the fuel filter and possible tune-up

Could be caused by a few different thing's ,dirty mass air flow sensor ( if your vehicle has one ) A worn TPS - throttle position sensor , dirty throttle plate .

The cabin air filter is located under the cowl. Open the hood, proceed to the passenger side of the car and you will see where the right side wiper is resting, under the black plastic cowl there the cabin filter is.

Im not quitre sure but did you bleed the system...on the fuel rail on the intake there is a zert fitting like a tire valve try bleeding the system could be trapped air

The owner's manual calls for changing oil and filter every 7500 miles in normal service, or if driving in dusty conditions, offroad, or lots of low speed and idling (a taxi or maybe an unlucky commuter), go to the extreme service intervals of 5000 miles. Changing oil every 3000 miles is definitely NOT required.
