Carly does not always spit out the correct error codes, so my experience
Better would be a program like INPA to read the error memory

But so that I understand everything correctly and we do not talk past each other:
The errors occur only in colder weather conditions?

Says the guy who drives a M3

I only started it three times. The last start the idle smoothed out and I got the increased emissions error. All starts were cold.

Here are my errors. Can anyone decipher this?

Thanks

I also received....

00A834 as a unknown DTC fault
009C7B Interior Sensor Blower
009D14 Errors in the protection circuit.


Any feedback would be appreciated.

Thanks

Ok I did some research. I think my issues are either spark plugs, coils, O2 sensor, idle control valve or battery.

What else can cause multiple cylinder misfires?

Can anyone help out the mechanically challenged (me) ??

[wchow16]

I cleared my codes and I checked my battery and it is healthy. Starts have smoothed out so I took it out for a short drive. No issues and the errors have not returned :
