Assuming that this is an 8 cylinder engine, you should be able to remove the wire plug going to the coil and then remove the 8mm bolt that holds the coil in place. (The number 4 cylinder will be the farthest one from the front on the passenger side.) You may have to try to rotate it back and forth in a twisting motion after the bolt is removed to break the rubber boot loose from the spark plug. The coil can be purchased at your local auto parts store. Make sure you replace the rubber boot as well. If your engine is a 6 cylinder, the number 4 cylinder will be the one in the front on the driver side and will be easier to access.

Misfire on Cylinder 3 swapped plugs between 3 and 4 on Pontiak Aztek 2003. Misfire remained on cylinder 3. Swapped ignition coil 3 and 6 with ignition coil 1 and 4 misfire still on cylinder 3


Try a new plug wire on cyl 3 if that doesn't fix it you could have a bad valve or compression problem on cyl 3 Try doing a compression test also If it has injectors for each cylinder you could have a bad injector for cylinder number 3

Spark plug wire diagram for 2005 mazda 6


2.3L 4 cylinder? After removing the plastic engine cover, look at the top of the ignition coil.

changesparkplugs003.jpg
It should be numbered 1 through 4.

This is plug number 1 on the engine:

Just wire them 1, 2, 3 and 4 to the corresponding numbers on the ignition coil.

I removed my spark plug wires and forgot which wire goes with which plug for a 1998 toyota camry.


moz-screenshot.pngmoz-screenshot-1.pngmoz-screenshot-2.pngThe firing order is 1-3-4-2

Number one is the one at the pulley end of the motor and number 4 is at the flywheel end of the motor.

System uses a Distributorless Ignition System (DIS) with 2 ignition coils. Cylinders No. 1 and 4 use the same ignition coil. Cylinders No. 2 and 3 use the same ignition coil.

How do I find the #4 fuel injector on 2005 town and country?


What size Engine?
The Number 4 fuel injector goes to Cylinder #4.
On 3.3L and 3.8L it should be the Front Middle Cylinder.
If you are not sure where Cylinder #4 is. Look on your Electronic Ingition Coil = Distributor. It has small numbers on them #1 thru #6. The numbers are small and black, but they are there. Follow that #4 wire to Cylinder #4. Fuel Injector #4 should be right over the top of that Cylinder. Usually the Cylinders themselves have numbers on them on the engine block, but it is easier for use to use the Ignition Coil as a reference.
Cylinders Numbers should be:
1 - 3 - 5 Rear
2 - 4 - 6 Front
Ignition Coil should be:
6 - 3 Rear
4 - 1 Middle
2 - 5
Let me know if that helped, or if you have any additional information, problems or questions. Feel free to contact me at FixYa.com!

Need firing order and, I need to know what side the number one piston is on?


To avoid confusion, remove and tag the spark plug wires one at a time, for replacement.

The 3.5L (VIN H) engine's unique ignition system has the ignition coils directly over each plug. No spark plug wires are used.
If a coil is replaced on any of the 3.1L, 3.4L or 3.8L engines, it may not be numbered, as is the factory coil. 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 in your guide to reflect how your engine is wired.
