Weird starting issue?!
Okay I'm new to this, but.. I replaced the lower intake boot on my 330i as there was a massive crack in it and walah all my rough idle no power problems went away... so my bright idea lets disconnect the battery and see if CEL goes away... so now the issue is when you first start car it has barely any power rpms are fluttering from 0-500 seems like it's going to shut off for about five seconds then it jumps up and idles fine?! I have no idea what I did or what could have happened? Could somebody supply me with any info on this? And yes cel is still on for the same codes as before and I do believe this is directly related to battery issue as it started fine multiple time before doing this.
