Having problems with your 1999 Mercury Mountaineer ?
Do you need to change spark plugs on 1999 mercury mountaineer i was told they never needed changing also why would it stall or die when cutting the wheels a little sharp
Yes they eventually need changed. If you never had a tune up your probably due. Plugs, wires ,cap,rotor,airfilter, and fuel filter. All these affect the performance of the engine. Looses power, and can make it stall or cut out under loads, like when you make hard turns and the power steering pump is putting a load on the engine
They dont make such a thing as lifetime spark plugs. Even iridium plugs only are good for around 100000 mile. Definately start with a good tune up. Make sure when you get the tune up done they do a throttle body service as well.
