hey yall. I have a '99 328i. every morning when I start up, the engine runs rough. about a minute into the warm up time, every 10 seconds, the engine takes a dive like it's going to die out, but picks back up again into the 1k range. this continues until the engine warms up, and doesnt do it anymore. Even when I go to work, leave in sitting all day, and on cold evenings when i'm going home, it does this. the other thing i notice on the thermostat, when it gets above the line (1/3 mark) it will stop, anything below that, the engine runs those 10 second intervals until the engine warms up. looking forward to any suggestions. thanks.
