Check engine code 1222 (archive)

Hi all,
I'm getting a 1222 code on my check engine light in my 94 740iL, M60 engine. I was previously seeing 1221 codes as well. I took it into my regular BMW service shop (independent BMW service, not the dealer) and they saw the code, but it later disappeared. They said the oxygen sensor wasn't getting power, but when they checked it later everything was okay. Anybody have any ideas what to look for? It seems to happen only when the car is cold. Once I'm out and the engine is warmed up, it disappears.

Thanks,
Tom
