you may have a bad coil---take a pair of rubber handle plyers & remove the spark plug wires 1 at a time---when you pull off a plug wire you should notic the truck runs even worse---the one you pull off & it doesnt change the way it runs--that is the cylinder that has the problem

SOURCE: code p0401-exhaust gas recirculation flow insufficient detcted

these vehicles as well as every other Ford vehicle has had problems with the DPFE sensors going bad. Ford had a program for this problem but was limited to time and mileage. You can contact a dealer to see if it still qualifies if not the sensor will need replacement. this is very easy to replace

SOURCE: cant get spare tire off

The metal sleeve on the end of the cable,you turn it sideways and push it thru the hole in the wheel. If it is stuck to the wheel just pick up on the wheel then tap the sleeve with a hammer.

SOURCE: How do you access the spark plugs 2002 mercury mountaineer

IIRC these are a coil over design. meaning the coil is over the plug. the coil should have one 8mm bolt holding it on the lower intake manifold. remove the coild to get to the spark plugs. look by the fuel injectors, coil should be just next to it or very close. coil usually says motorcraft on it and circle in design.

good luck

SOURCE: I want 2 change 2004 mercury mountaineer transmission fluid

The best way to change it is to flush it out You can do it yourself, but I do not recommend. A shop that is good like a Monro or Firestone usually charges about 100 bucks to flush and that includes the fluid. If you do it yourself, you will save about 60 dollars, but you risk damage to your radiator.

you will need a hose and an adapter. you back out the lower, or upper cooler line for your trans, whichever is the easiest to get to, (Some trucks have an auxiliary engine oil cooler, but make sure you are flushing the trans lines) put the adapter into the rad where you removed the line, and put a hose from each one down into a bucket. Have about 14 qt's of ford trans fluid ready. Put the funnel into the trans dip stick, and start the engine. pour the qts into the dipstick tube while the old fluid is pumped into the bucket. When you have about two gallons pumped into the bucket shut the engine off and reattach the line into the radiator. start up the engine and check your level. Fill with additional fluid if needed.

note: some say you should drop the pan. two things, you only change half the fluid when you do it that way, and second if you need to change the filter because it is clogged, it is too late for the transmission. The filter is only there to protect the valve body, not keep the fluid clean.

Hope this helps

Is that the only wire with a metal boot? IDK, maybe it's an indicator for number one cylinder. I can't imagine any reason to put a metal boot rather than a rubber boot.

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
