Hello,
I have bought my first ever E92 320i from 2007 (automatic transmission) with 105000 km three months ago. It has been working and running as expected. However, three weeks ago i started having troubles with the engine running cold, it will struggle very much, keeps misfiring and shivering. In addition, the engine bay smells like fuel all over it. After running the engine for like 15-20 minutes, it suddenly goes back like nothings is wrong with it and runs like a champ.

I have already changed the plugs and the coils but it keeps misfiring and doing the same thing over and over. What might be the issue?
