Lose the plantinum plugs. They are not suggested for supercharged cars.

Use an ohm-meter to check the resistance of all 6 wires and report them back here.

Use Techinfo to check all 3 coils and report the numbers back here.

Use a scantool to determine exactly what cylinder is misfiring if possible, and report any codes back here.

Inspect all 6 spark plugs and take a closeup pic and post the pic back here for us to help you read your plugs. Keep them in order and mark them for what cylinder they came from.

Yes, firing order can cause a misfire. Get it corrected. Facing the engine, 135 in the front left to right. 246 in the rear left to right.

Don't ever let autozone test anything for you. Please do the checks I listed above or we can't help you.

The front middle plug IS the #3. So what was the other one?

You didn't post any of the numbers. How do you know the wires were good? What resistance did you record?

Where are the pics of the plugs? This is important. Also explain how you have the wires hooked up. Have you mixed up your coil order?

Here is how the wires, coils, and plugs are connected:



Make sure they are connected as shown. Ignition wires are fragile. When you remove the wire boot from the plug or the coil, twist, then pull on the boot; be careful not to pull on the wire. That can cause the conductor that carries the current inside the wire to break without you being able to see it. That is one reason why you need to use a little silicone dielectric grease on the inside of the boots - to make removal of the boot a little easier. This happens a lot on the back wires where it is more difficult to get your hand on the boots. It sometimes helps to lie down on the engine so you can reach those back boots more easily. A broken internal conductor will cause a miss, sometimes intermittent. The routing of the rear wires is also pretty important. Keep the wires away from the oxygen sensor wiring and don't let the #6 wire rub against the bracket with the fuel lines. This can also cause a miss.

So, even though your wires are new, you may have broken one taking it on and off, and sometimes it is possible to get a bad wire right out of the box. That'* why willwren is asking you to test the resistance of each wire. To test whether you have a broken internal conductor, connect an ohm-meter to each end of the wire, then pull on the wire and wiggle the ends around and make sure you do not lose continuity.

I used to re-use ignition wires routinely, but in recent years, I have become more careful about re-installing wires. Some newer, radio suppressing ignition wires use carbon fiber conductors that are surprisingly brittle and easy to break internally. When exposed to heat over time, the wire components can deteriorate and are even more likely to break. The breakage usually occurs when the wire is being removed. That is one reason that it is a good idea to change wires when you change plugs. If you get the wire routing right the first time, and have never removed a new wire, you can be pretty confident that the conductors are OK. But, if you have had problems and had to remove and re-install them several times, the likelihood of breakage is increased.

Just to clarify: Firing order is the order in which the cylinders fire and for this engine is 165432. Because our engines have no distributor, knowing the firing order offers little help in properly connecting the ignition wires between the coils and the spark plugs. Cylinder numbering follows different conventions depending on the manufacturer. For many engines cylinder #1 is the cylinder closest to the front of the engine. The front of cross-mounted engines is the end where the belts run. Some manufacturers of V6 engines number one bank odd and the other even; other manufacturers number them as you guessed: 123 on one bank, 456 on the other. When working with different engines, you need to check to be sure how your cylinders are numbered. So, what you had confused was cylinder numbering and consequently wire routing.

This is why it many recommend to change out one plug and wire at a time. That way, if the car was running properly before, it will be running properly after you change out the plugs and wires.
