My 2006 325i has been starting rough lately, on cold starts, warm starts, and sometimes idles weird. Just to note I did do a 3IM swap and I had trouble getting the oil separator to fit onto the new manifold so it is not mounted and I did "plug" the second hole on the manifold with duct tape. The disa valves are good, I just swapped the solenoids to another set and it did not improve the start ups or idle. Plugs were changed about 8k miles ago, but I did pull them today and noticed there is a little bit of oil in the well, which we had a problem before where we had to replace the gaskets to fix a oil leak in the wells. I do also notice while I'm giving light throttle the cars rpm seems to drop a little and hesitate instead of flowing through the Rpms this happens around 1500-2500. any help would greatly be appreciated because I am stumped with no Check engine light. I tried adding on the video of my cold start But it won't let me.

I know it sounds weird, but have you checked your purge valve? it can lead to improper combustion, as for the oil, try tightening that bolt in between the plug boots. the tube seals are separate from the outer vc gasket.

I actually haven't checked the purge valve. And what bolts are you referring too ? I know the VCG and seals are different because I've already replaced both.
