Hi everybody. I have a 2004 330ci automatic. The engine started idling roughly and misfires. Sometimes even stalls and there is a huge power loss. The misfire is almost like a popping sound coming from the manifold. I was planning on selling it but this happened. I am a huge bmw fan. This is my 3rd one. Anybody experience this before and what could be the problem?:blueCry:
