Please help. Lots of engine code errors.

[stockysnail]

Last night I opened the hood and pushed on my header flex joints to make sure they were ok. I also looked at other stuff. This morning the car sounded weird, under powered and sounded like one of the cylinders wasn't working as the UEL sound was much more pronounced. All I could think of was when I was touching the UEL headers so maybe it isn't sealed onto the engine anymore (became loose).

If anyone would like to come over tonight to help figure it out I'd appreciate it. (if I can make it home from work)

My scanguage gives me the following error codes:
P0202 - Cylinder 2 Injector Circuit Malfunction

and these shortly after the one above most of which I can't find descriptions for:
U3237
U3337
U3238
P0B37 - High Voltage Service Disconnect Open
P0F37
and many more.

Try resetting the ECU? You have a copy of your tune that you could use to attempt a re-flash?

I had my computer throw a bunch of random errors a while back due to my bluetooth dongle causing some can bus communication issues. I reset and all was back to normal, but I didn't have any mechanical symptoms at the time.

I pulled my car over a couple times, turned it off, and cleared the codes. Each time it seemed ok for a couple minutes but then went back to seeming like it was running without one of the cylinders. I don't have a dongle, the flash file or anything but I could contact Moto-East if I need to reflash or something (with someone's borrowed cable).

You can probably guess where I'll be after 6. I'll have tools with me.

Hopefully you can get Matt's car working. Put me on your list after you get his working.

Can't make it out tonight. If you're still having issues I'll be able to stop by some time this weekend?

Your analysis reminds me of an old joke I heard about UEL equipped Subaru.

Mechanic 1 "How do you know if a modified Subaru is misfiring?"
Mechanic 2 "I don't know"
Mechanic 1 "Me neither"

After work I got in my car. I cleared the codes. Started the car. Sounded normal. Sat there a few minutes and no codes and seemed normal. Drove home and even stopped at a couple places on the way. Everything is normal now.

No idea why it decided to crap on my morning but now it's fine. I didn't do anything different. My gas was low this morning but not any lower than it's been in the past, plus I filled up on the way to work, limping along with 3 cylinders. Maybe my car's pissed that I didn't wash it or I took off the side skirts to sell them. Or maybe Matt's luck came to my car so his would work out great.

Hmmm. Interesting theory...

My car worked fine again this morning. Maybe it was a weird issue with me being low on gas the other morning and it needed to sit with a full tank for a while. Who knows.

I just started my car today for the first time since last night. I'm getting similar engine codes are I was back on July 1st. Not sure why it ran fine late July 1st until now.
Engine codes:
P0202
P0032
P0033
P0034
P0037
P0038

I look at the engine and everything looks ok. WTF is going wrong? I don't want my car to stop working before next Sunday's 86 meet!!!

Where are the coil packs and how would I go about swapping two different cylinder's coil packs to see if that's the issue?

Here's my standard trick. Without removing any of the coil packs, disconnect each one and listen for the idle to drop. If it does, reconnect and move on because that one is ok. When you disconnect the bad one the engine won't run any rougher. Make sense?

The packs are way down just inboard of the frame rails. The connectors stick out the rear-facing side of each coil pack. It's tight down there but, while the engine is cold, practice disconnecting one and then see if you can plug them in just shy of clipping them. Then you can disconnect it, decide, and then reconnect it if it's good.
