I forgot to plug in my intake vanos solenoid for a week after ccv...I looked and looked...my damn mechanic found it in 5 secs.

Are you sure you attached the engine ground straps by #6 cylinder when you did plugs and coils?

Do you have an OBDII scan tool that can display Live/Real Time data?

Read this about OBDII tools - http://forum.e46fanatics.com/showthread.php?t=967204

Did you possibly swap the O2 sensor connections when doing other work on the engine?

Check the 1st link below in my signature for other problem areas.

Not sure where you are located, might be problem fuel due to super cold weather.

I believe there are fuses for the O2 sensors, check those.
Did your mechanic advise you on this?

I changed my air distribution/spreader o-rings, they all looked very bad. It's pointless to do a CCV job and not replace these as they all add up to a big vacuum leak. Also change all of your vacuum hoses, one at a time so you don't mix up anything. Mine were brittle and split.

Looks like your transmission is in limp mode. Mine does that sometimes. When it does I turn the car off for a minute then it goes away. I still don't know the cause.
