'05 330i hesitation and uneven idle

Hi all,

I recently bought this car and in past few days I started noticing uneven idle. RPMīs are changing from about 550 to 650 every Half a second(right after cold start, when RPMīs are higher, idling seems smooth).

Then it is also hard to take of smoothly in first gear and when changing lower gears in lower RPMīs car jerks most of the time.

And also the hesitation under WOT, part -throttle or off throttle in low RPMīs. When I mash the throttle at low RPMīs in higher gear(4,5,6) car accelerates, then usually around 1500 RPMīs hesitates/jerks and then everything is fine up to redline.

I can make some videos, if that can help

After what I have red, I am thinking that it might be coils?

Thank you in advance and sorry for my english, I am not a native speaker
