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: how do you change the spark plugs on a 2003

  1. Most of the 4.6 Litre engines have some form of plastic cover, mine was held in place with two 11mm nuts at the front and press-fit connection at the back. Remove this cover to gain access to the spark plugs. You may need to disconnect the air hose going to the throttle body and some additional vacuum hose connections. Mark them with masking tape and numbers if you have any question about re-attaching them correctly. Along each side of the intake manifold you will see 4 round coils held in place with a 7mm bolt on each one. Remove the 7mm bolts from each coil. Each of these coils has a connector that will be disconnected by pinching the connector to release the catch and pulling gently. Do not worry about marking them unless the wire harness has been modified. The factory wire harness keeps the connectors next to the correct coil.
  2. Remove each coil and plug connector by gently turning the unit to break the rubber loose from the manifold, then pulling up on the coil/plug connector as a unit. Do not be alarmed if the rubber boot cover comes off, you can easily reattach it to the coil. Once the coils and rubber boots are removed, use your compressed air source or vacuum to remove as much debris from around the spark plugs as possible. Warning: Wear Eye Protection when using compressed air.
  3. Remove the spark plugs using the 5/8" spark plug socket, swivel, extension and ratchet. Some engine installations may require additional extensions or swivels to get the back plugs removed. It normally takes just an 1/8 turn to break the plugs loose and then about 4-6 full turns to fully remove the spark plugs. If the plug does not come out with the socket, use the magnetic pickup tool to pull the plug out. You will not be able to reach it with your fingers.
  4. Using the feeler gauges gap your new spark plugs to the correct gap for your vehicle. A typical spark plug gap for this engine is .054 inch. With the plugs gapped, fit the rubber fuel line to the top of a spark plug and then apply a small dab of anti-seize compound to the plug threads. Work the anti-seize into the threads a little bit and then insert the plug into the engine. The rubber fuel line will prevent you from cross-threading the spark plug and you should be able to turn the plug in about 3/4 turn or more easily. If not, remove the plug and make sure that it has not picked up any debris in the threads. If so, clear it out and try again. Once you have all of the plugs started, use the 5/8" socket to tighten them just 1/8 turn past their stopping point. Do not over tighten as this is the leading cause for plug-blowout with this engine series.
  5. With all of the spark plugs back in, you can then proceed to replace the coil/plug connectors. Replace the 7mm bolts for each coil and tighten them snugly but do not over tighten. With the bolts tight, the coil/plug connector should still rotate slightly. Reconnect the electrical connectors for each coil by gently pushing them in place until they click. They are indexed and will fit only in one direction.
    Reconnect the air hose to the throttle body and any vacuum lines that were removed. Replace the plastic engine cover and fasten it in place. That's it, your done.

Im sorry,its a 1997 ford 302 (1997 mercury mountaineer) codereader indicates 'no. 7 cylinder misfire'


remove the #7 spark plug if it does not look fouled start the vehicle with the plug still connected and look at the ground electrode for any spark it should be a white arc which indicates a high intensity spark if its orange/red it is a weak spark. If you get a poor spark try removing any other spark plug and test it on the #7 coil wire If you still get a poor spark then your plug wire or ignition coil is to blame and would need to be replaced. You can swap your plus wire to test it in the same way as well. hope this helps

No spark


An Ignition system check is required to see if there is voltage going to the Ignition coil. Use a fluke meter or multi meter and check the connector from the coil pack. Or, ohm check each spark plug wire individually and one by one.

My mountaineer shakes like a motor mount is broke. there isn't a mount broken


check all spark plug lines ... that shaking could be one plug not firing causing a out of rythem engine vibrations
if they are all connected then try disconnecting plug wire hold plug wire near metal near plug end to see if its also firing YOU need to hold plug wire back a little from the end or it will arch to your hand not pleasent shock ...

Could be a lot of things,
Check spark plug wire
Spark plug
If those are good, get a compression test done to see how the cylinder is.
You could also have a bad fuel injector, which will not deliver fuel.

I need to know the timing sequence for a 1998 Mercury Mystique 2 liter


ignition timing or valve timing?

ignition timing not setable.

info:
The ignition system consists of an ignition coil, spark plug wires and spark plugs.
The crankshaft position sensor signal is the basis for ignition timing calculations. The alternating voltage signal from the crankshaft position sensor is digitized by the powertrain control module. This digitized signal is then used to position the closing time of the primary circuit of the ignition coil.
Ignition angle is determined by the powertrain control module in response to engine operating conditions. Once ignition angle has been determined, the powertrain control module interrupts the current to the primary circuit of the ignition coil thus triggering the ignition spark which is supplied to the cylinders through the spark plug wires and spark plugs.
The ignition coils are triggered by the powertrain control module in pairs (cylinders 1 and 4 and cylinders 3 and 2) sending one ignition spark to the firing cylinder and one ignition spark to the corresponding cylinder on the exhaust stroke. This make sures that any unburnt fuel residues remaining in the cylinder on the exhaust stroke are re - ignited to provide cleaner exhaust emissions.
