got a cold air intake? i was using a shot ram style CAI on my focus, it had the same symtoms, i replaced it with the stock air box and it went away. every winter now when the temp gets to low i always switch back to stock. what i think is happening is when the CAI in on, its taking in to much cold air and the PCM tries to compensate, making it run rough and rich at idle. .....
