misfire after battery reconnect

[92cleanbeam]

I pulled my car into my garage and unplugged the battery. I fixed my tailight bulbs and a brake light. After all this I plugged battery back in and now it wont start. Well it will if you hold the pedal down, but it acts like its flooded. Is there a reset for the car or something?

This is EASY...
Get her running and leave her for five minutes... (BMW do not recommend Tick-over for long periods).
Take her for a decent run as the ECU may want to learn some sensor readings after the battery disconnection...
The moral of the story is that these cars rely on computer info...
Therefore disconnecting the battery sometimes resets the car to "Limp" or "Factory" settings...
Give it a go anyway.

Well I held it to the floor and the car barely stayed running. It was definitely getting too much fuel because it started to smoke a little bit. Its just really rough. I find this quite amusing because its my first BMW and its just a commuter car. Its funny that a battery disconnect could do this to a car. Anyways I will try again.
