Firing order for spark plug wires for a 2006 dodge durango 5.7

Checking the firing order and that you have wires in correct order would be first step.

Look in the 1999 service manual it has the correct firing order.

FIRING ORDERS

Before carrying out extensive tests to isolate poor running problems, check connections of spark plug wires. This is especially important if plugs, wires, distributor, etc., have been disturbed recently for service. Obviously, this is not applicable to the wireless 4.7L engine.

NOTE To avoid problems, remove and tag the spark plug wires one at a time to ease reinstallation.
For vehicles with an extensive service history, keep in mind that the distributor could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason, it is very important that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired.

It is a V-8 so 8 spark plugs.

Firing Orders NOTE: To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.
If a distributor is not keyed for installation with only one orientation, it could have been removed and installed improperly and then rewired. The new wiring arrangement would maintain the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes of the current plug wire locations and orientation of the distributor cap.

Firing order: 1-8-4-3-6-5-7-2

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.

For the 4.2L:
Firing Order:
1-4-2-5-3-6
Cylinders:
3----------6
2----------5
1----------4

The firing order is a sequence of ignition time when the engine cylinders deliver their power-strokes starting with the number-one cylinder. If this sequence is faulty or arranged disorderly, the engine may not start at all, and if it does start, it may does so hesitatingly, or not run enough well to enable it to drive-or simply lacks the power to move. A waste of gas, and unecessary tear and wear on the engine and its critical components ultimately result. Once the firing oder is correc and in proper sequence, the engine should starts easily and promtly, running as quietly as posiible.

For Dodge 2004 Durango firing-order:
All 6-cylinder K 3.7L MFI SOHC distributorless ignition:
1-6-5-4-3-2 (front 2-4-6) (back 1-3-5)

All 8-cylinder N 4.7L SFI (including HEMI 4-WD)
1-8-4-3-6-5-7-2 (front 2.4.6.8) (back 1.3.5.7)
(distributorless ignition)
It is also a good thing to try and compare the thread lenghts of the old spark-plugs being replaced with the new.

I hope help you with this. Good luck (remember rated this help).

1-8-4-3-6-5-7-2. That is the firing order. Cylinders are 1-3-5-7 on the drivers side of the motor, 2-4-6-8 on the passenger side. Distributor should spin clock wise. Set it up on #1 TDC, and run the plug wires around cap off that one being #1.
