Typically, Its a matter of removing the leaking injector, Removing old o-ring(s), lubricating new o-ring(s) and gently re-installing assembly. once done, plz check for leaks to ensure injector sealed once running. Hope this helps.

    For safety sake also make sure to depessurize the fuel rail before taking out the injector; gasoline is quite flamable!

SOURCE: airbag light on what does that mean

It means that your airbag system is not fully functioning and you need to have the dealer check it out. Whenever the airbag light stays illuminated after starting the vehicle, it means that there might be a problem with the air bag system and a check up is needed ASAP to make sure the system will operate properly in the event of an accident. It could be a faulty sensor, or it could be that a wire or connection is loose, etc., in any case, the dealer will need to check the airbag system to determine what the problem is.

I had a situation where an stereo installer had probed the wires in the airbag system and that caused the system to become non-functional, due to having voltage applied to the airbag wiring where it shouldn't have any voltage. It was an expensive fix, as he'd actually stripped the wires bare and he crossed several. Cost him a bunch to replace the wiring harness on my new vehicle.

SOURCE: Where is a fuel filter located on a 2002 mercury

Here's a step by step, with photos, on how to replace an Explorer fuel filter. The Mountaineer should be exactly the same. The problem you describe can be attributed to the fuel filter. Good luck.

I have a 2002 mountaineer it fills like it has a misfire but no code come up

Add a fuel additive to the tank to clean the injectors. Keep an eye on the service engine light. When it is constant it will show up..If you do not want to wait, then have a scanner put on and they can tell which cylinder is miss firing.

03 Mercury mountaineer not running right its flooding

Use fuel pressure test gauge to see pressure at key on, pressure when running, then watch gauge as you turn engine off to see if it rapidly leaks down. If so, you have injector(s) leaking.

2002 Mercury Mountaineer will not go anymore than 5 miles and hour. It starts and idles fine but seems to get bogged down when the gas is peddle is pressed. Is this a problem with the cat converter?

if your exhaust smells like rotten eggs then yes ,,if not you need new coils and plugs/wires ..My thinking from what you stated is that you have a stopped up fuel filter and injectors need cleaned ..I am 90% sure of the later part

Stalls when steering wheel turned to left

Could be incorrect idle speed, fuel filter clogged, water in fuel, damaged distributor cap, and wires, plug and plug wires defective, not all one or more, Vacuum leak at intake manifold or hoses, fuel injectors needs cleaned.

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
