How to interpret these engine codes

Today, my check engine light went on. With the Peake R5/FCX-3, I get these codes on my 1999 323i:

1. F3 misfire cyl#6
2. EF misfire cyl #2
3. A8 electrical thermostat mechanically jammed open
4. 41 camshaft sensor, intake cam
5. E3 O2 sensor adaptation limit on cyls 1-3
6. E4 O2 sensor adaptation limit on cyls 4-6
7. CA O2 sensor control limit on cyls 1-3
8. Cb O2 sensor control limit on cyls 4-6

These don't look like they portend a catastrophic problem if I continue to drive. The car seems to be running fine.

I did have a problem a few weeks ago that indicated something with the electrical thermostat stuck open, and the engine ran rough. It has happened 3 or 4 times while driving in stop and go traffic. (Transmission is manual.) Each time, I could reset it by restarting the car. This didn't work on todays problem.

Yesterday, I replaced the car battery, and at the same time the passenger front door wouldn't open. I'm inclined to think this is unrelated, but who knows with electrical problems, sometimes.

Anyway, would someone care to tell me what might be happening here, with each of these codes?

Misfires happen, and get recorded, so I have seen them before. (I don't think they cause the CE light to go on, though.)

I don't know anything about the O2 sensors other than they control emissions and optimum engine operation.

I don't know where the "electrical" thermostat is located. (The engine temp looked a little low, so stuck open sounds right.)

And camshaft sensor, intake cam? Sounds like timing issues. that might lead to O2 sensor faults, but I'm guessing.

I want to try diagnosing this at home, first. How should I start?

Personally I would say when you have a camshaft code replace that camshaft as soon as possible. I let my intake code come back a few times and the car stalled on me twice before replacing it. make sure to get OEM. Job is very easy and should take 20-30 min

What happened to your cam shaft? Could you see wear or damage? My engine has 181,000 miles, so I'm guessing it was just wear. My first reaction is that that's hard to imagine, but I have to trust your experience.

I think he meant the camshaft sensor, not the camshaft itself.

Haha! I couldn't see replacing a camshaft in 20-30 minutes. It's been awhile since I have looked at taking the head off one of my engines. The camshaft wasn't so easy, without a special tool ,as I remember. (With the tool was a different story.)

I'll be ordering a sensor on Monday.

Pretty safe to say replace the cam sensor and the thermostat and see if the O2 sensor codes go away. I've had those O2 codes twice before. Once it was the MAF and the other time it was thermostat.
