I have a 1998 Ford Explorer 4.0 single overhead valve. I disconnected the spark plug wires off the coil, and forgot how to put the wires back on. Can you help me please?

Hi:
A code P0304 - 305 or 306 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer

Possible Solutions:
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

It is possible that that particular cylinder is getting enough oil to the plug (seeping by the rings or valve) to foul it out after a period of time.

I don't have a link with pictures, but I will describe the cylinder and coil numbers for both the overhead valve (OHV) and the overhead cam (OHC) as best I can.
Facing the engine from the front bumper.
On the 3.0 overhead valve (OHV) the cylinder location looks like this:
1 2 3
4 5 6

The coil location looks like this:
5 1
6 2
4 3

If you have the 3.0 overhead camshaft (OHC) engine again facing the engine from the front bumper your cylinder location looks like this:

1 2 3
4 5 6

Your coil location looks like this:

4 6 5
3 2 1

I hope this was helpful.

Haynes repair manual.
I didnt put the first five in becuase of the things you said the vehicle is doing you didn't need them. but this is straight from the Haynes manual
6. water in fuel
7. wet or damage ignition components
8. worn, faulty, or incorrectly gapped spark plugs
9. Broken, loose or disconnected wires at coil or faulty coil
10. timing chain failure or wear affecting valve timeing
11. Fuel injection or engine control system failure

put a screw driver into the plug that you think is missing get it one forth of an inch away from a good ground and crank the engine over if there is spark try replaceing the plug or plug wire or both, and if there is no spark if that model has a distributor replace the cap and rotor and wires otherwise if it has the coil pack you will have to change the coil pack.

you might want to replae the map sensor and or the egr valve either of them can make it backfire
