Replace coil packs on the ford explorer 2006

Are you needing the firing order of the ignition leads to the spark plugs? It would depend on what engine you have, but look closely at the coil pack modules. I belive Ford have the number of the cylinder marked next to the output on the coil connector for each cylinder.

you have a bad spark plug wire on cylinder 4 or your ignition coil
(coil pack) is bad.

here is a good guide to testing coils and wires if you need it
How to Test the Coil Pack Ford 3 0L 3 8L 4 0L 4 2L

Then you went to a shop that doesn't have the
skills necessary to resolve much,cylinder misfires
in your case

You never need a MIL Lamp, to check for codes,cylinder
misfires & other data

Code 71 is for a problem with the air temp sensor.

its faulty coil.

Get the compression test done on each coil.these will let you know if its faulty coil or not.

=========

It can be issue with spark plugs or faulty spark plugs. Also get the compression test done for cylinders. If any of cylinder shows low compression then required, then that particular cylinder will cause misfire.

Also get obd codes scanned, the error code will let you know which cylinder is misfiring or all cylinders are misfiring.

This will help.

Thanks.

Check out autozone.com. Once you register you can look up all kinds of information for your vehicle. How to information, wiring diagrams, exploded views, firing orders, diagnostic code information, etc. As far as I know the 94 explorer had a 4.0 liter with distributorless ignition. Are you sure you have a 94 explorer with a 4.0 liter engine? On the 4.0 liter the passenger side of the engine are cylinders 1-2-3 the drivers side is 4-5-6. The cylinders should be labeled on the coil pack. The passenger side of the coil pack will be cylinders 1-2-3 from front to back. The drivers side is a little tricky. From front to back it will be cylinders 5-6-4. Lt me know if you have any questions. http://www.autozone.com/autozone/repairinfo/repairguide/repairGuideContent.jsp?pageId=0996b43f802c54b3

code says #3 cylinder misfire, check the coil pack for this cylinder to see if its got spark, bad o2 sensor will spit another code, its most likely the coil

Hope this helps. The ignition coil:

• changes low-voltage pulses from the PCM to high-voltage pulses.
• fires 2 spark plugs simultaneously.
• has 3 transformers.
  • One transformer fires the spark plugs for cylinders 1 and 5
  • One transformer fires the spark plugs for cylinders 2 and 6
  • One transformer fires the spark plugs for cylinders 3 and 4

Spark plug wires:

• carry high-voltage pulses from the ignition coil to the spark plugs.

The spark plugs:

• change high-voltage pulses to spark at the gap, which ignites the fuel and air mixture.

The firing order is 1-4-2-5-3-6.

1997 Ford Explorer 2WD / 4WD
4.0 liter SOHC V-6 VIN "E"

Firing order 1-4-2-5-3-6
cylinder # passenger side front to back 1-2-3
Cylinder # driver side front to back 4-5-6

Coil pack # passenger to drivers side firewall 1-2-3
coil pack #passenger to drivers side radiator 5-6-4

The code description is a giveaway.
It could be one of the coils on the coil pack. Most coils nowadays do two cylinders each. This way car makers can get away with one coil for two cylinders.(lowers costs) One spark fires the air fuel mix in one of the cylinders and the other will fire the cylinder on the exhaust stroke. If the coils are removable, and you are fairly handy with cars,switch two around, the problem will follow the bad coil.
