E90 super sluggish start

[Drymite]

So its been recently getting colder in toronto and my e90 n52 has a super sluggish start and sometimes wouldnt start until 2-3 times of trying. My coils and spark plugs where changed I believe its a vacuum leak. I got the code running lean. And i have random misfires before coils and sparks reason why i changed them... sometimes my car would turn idle rough af over rev while i drive for like 1km then everything goes to normal. I think its a vacuum leak but not sure because 2 winters ago when i had a nasty vacuum leak the car would turn on and turn off instantly and that was only in the cold.,., also after my engine is warm and i turn it on it. It doesnt hesitate to turn on like first start in morning...
Anyone have this problem ?

So the engine is slow to turn over then start, if so I would check battery health and consider replacing the starter

Hard to tell with all the rambling and back-and-forthing, but I think OP means he's throwing a lean code.
OP, are you currently throwing codes? If so, what?

Battery is new agm crank i got replaced since i still had warranty.... starter could definitely be going since the vehicle is at 310k km and i been driving it since 190k km. But if the starter is going wouldnt it start sluggish all the time. Because after my car is warmed up it turns on instantly

Exactly. The symptom set is not very clear, slow to crank or cranks a long time. Cranking slowly is a battery issue. I would not consider the Starter given the symptoms described.

What is REALLY needed here is a better description of the symptoms.

I'm sorry, but my read is "I lifted a big cover on the front of my car and there's some sort of huge metal thing in there with plastic covers and lots of wires, what's wrong with it?"

Okay battery is agm brand new ... sluggish start only after the vehicle has been parked for the night... i don't understand whats so hard to understand about it. Im saying somtimes it starts quick and sometimes example ill pull in into a gas station fill gas and i press the start stop button and its hesitant but always turns on .. the battery health is good. Im guessing its starter. If you have actual advice to share will be much appreciated...
