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

Check and see if you have spark at the spark plugs. Also replace the full filter, finally have someone check the computer fault codes.

What do I need to do to change spark plugs and wires on 1997 mountaineer


Spark plug wires just pull off and press back on. Make sure you grasp the wires by the rubber boot only. If you pull the wires by the wires, instead of using the boot, you can break the wires. Remove the plugs with a 3/8" ratchet, extension and a spark plug socket. I do not know if you have to remove anything to get access to the spark plugs and spark plug wires. You may need a universal joint to angle the ratchet.

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

Have a p301, p305 codes (misfires) and p401, Engine runs really rough. 120000 and never changed spark plugs. Could a simple tune up fix this. Also replaced the egr back pressure sensor. What else could...


It is most likely an ignition system problem so starting by replacing the spark plugs and wires ia advisable.

If the problem persists then have the ignition module, and coil packs tested.

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 ...

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
