Entire sensor. It was -11C yesterday and I still had the miss. Unfortunatley, replacing the sensor did not solve the cold rough idle problem.

Good to hear. In my case, I replaced all the coils along with a long list of things of other things, but still have the rough idle when cold.

Put my old temp sensor back in since it had been acting up with the new sensor.

Rough Idle in the Morning 2003 530i
For the last couple of months I have been getting a rough idle in the morning or when the car cools down typically 4 to 5 hours. When it is hot it runs good!
I went out and started up this morning after clearing the codes and it idled rough and within a minute or two check engine light came on. I turned it off and scanned it and I got a P1347 misfiring 3 cylinder. Is it possible I have a blown head gasket and during the night it leaks coolant into the 3 cylinder hence the rough idling?

Is there white smoke coming out the tailpipe?
