I think my coilpack packed it in
I was driving home when the check engine light came on. Pulled up to a re light and the car idled funny and it was running extremely rich with black smoke coming out the exhaust. I was a couple of blocks away from my indie shop so I took it there. They're going to scan it this week. What do you guys think happened. It sounds and feels like it's running on 6cylinders with smoke only coming out one exhaust pipe. The check engine light doesn't reset by cycling the ignition.

The tech scanned it and he's getting misfire codes on both sides. This morning it wouldn't start and he's worried it's hydro locked. He's going to pull the plugs. He finds it weird that both sides packed it in at the same time. Do you guys think it's the transformer or the coil packs or both?

had the same problem. it was the transformer. the tech couldn't diagnose it until i told him the symptoms. he pulled the plugs as well. short in the transformer, coil packs were also checked at that time and they were good.

So basically it would be in my best interest to get new coil packs and the transformer?

have it diagnosed properly. it should tell you what you need. if your just going to switch parts, expensive, i'd go with the transformer first and then coil packs.

i believe the tech did a visual inspection of the coil packs, apparently looking for carbon build up i think.

can you see what the part numbers are? you can take a flash light and it's on top of the coils..
You can also check for a minor oil coating on the red boots once you pulll the coil packs.. usually on cylinder 1 which is right below the oil filler cap, sometimes people miss slightly and it drips right into the spark plug hole and soaks the red insulators and shorts it but only when you gun it..
If you have the older part numbers, recommendation is to put the new ones in with new part numbers. I've posted a few times before what the new part numbers are..

I've confirmed that I have the old part numbers. I just want someone to look at the codes and tell me what is going on.

Are you doing the work yourself? With cost in mind, If it was me, I'd start with pulling all the plugs and looking at them. Their condition may explain a lot. You may have toasted/fouled them when the engine was running super rich during the misfires. OR perhaps there is a major internal oil leak that is killing the plugs which would then cause the misfires (if the fronts are fouled and the rears look clean). Replace all the plugs w/ the current coil packs and see if you still get the misfire (check again on what cyls). Then if the problem persists, I'd look at replacing the coilpacks on the sides you get the misfires. You can do that with a simple OBDii scanner.
Like the others said, check for oil wicking from the oil fill area to the passenger side coilpack connection and down into the plugs.
As far as the purge system, that's stored and not active. You probably left your gas cap off at some point, would be my guess as to that code. just my 2c. Good luck.

I find it interesting that with your problem, it is the front three cylinders (1,2,3 / 7,8,9) on both banks that are misfiring. When mine went out, there was one or two consistent cyls with misfires (#2 and #11 in my case) and then random jumping misfires of the others.

My indie mechanic is working on it. He just had enough time to pull the codes and he had to push it out of the shop. I'm hoping he's able to work on it this week.
He's pretty stumped because things just aren't adding up to point directly to coil failures. He can't figure out why the car was running so rich (nor can I at this point). I'm wondering if the cats are failed as well because when I was idling, it was only exhausting out the drives exhaust pipe. Nothing was coming out the passangers one.
On top of that, the car won't start unless you floor the gas pedal. Then it runs like its on 6 cylinders.
As for the purge system, I think there is something else wrong as I have already replaced the gas cap. That's the least of my worries right now.

Here's an update:
The car is fixed now. It was the ignition transformer. $900 including labor and it good to go.
