Mein Auto: 530i e61 2005
Smile E61 530i 2005 stuttering at low rpm after speedup (solved)

I have the following problem: From time to time (short jerks) when accelerating from 1500 -2000 rpm. Only with a warm engine.
Both in the D and on manually (I thought at first that the automatic transmission hesitated in D)
I once had a broken coil (jerking at high rpm and a message misfire)
Up to now I have seen no error message. Also via the OBD can find no message.
I already replaced the camshaft sensors, no change.
The MAF already replaced without result.
I've checked several readings:

Short term trim, bank 1: ranges from +6 to -10, -10 when accelerating, bank 2 idem.
Long term trim, banking one: always in the minus range of - 6 to -3.5, bank two comparable.
Apparently the mixture without correction isw to rich (excessive fuel pressure ??) I see on various forums that deviations from the Long term trim up to 20% is not really a problem). While stuttering (takes only few seconds) I do not see any weird values.

I read in an American forum that you can test the LMM, a rule of thumb is that the maximum flow that indicates the LMM in gr / sec. at maximum acceleration to about 5000 rpm, about 70 to 80% of the power in horsepower should be. this max value <65% then the LMM piece. I have tested this and come out at about 170 gr / sec. this is 170 / 258X100 = 66%. (Who knows this rule of thumb)
What I noticed is that the MAS remains at approximately 2 g / s when the engine is off.

Is there anyone who can help me further with the diagnosis so far.
Spark plugs, ignition coils replace I can do, but I expect they fail especially at high rpm

what could be the cause, or what can I test more. Could it be also the gas valve or?

The MAF sensor value should goes to 0 when the car off. How's the live stream data on the MAF sensor.

I am not sure if the same issue as yours but I have issue before with jerking if I drastically accelerate then the culprits were the spark plugs.
