hard acceleration: Engine Light & Rough Run. codes: 29CE, 2AAF

with your help dear friends I fixed the issue "reduced engine power" https://www.bimmerfest.com/forums/sh....php?t=1298207
but now have new issues.

previous: Im new owner of the 2007 335xi, all stock. previous owner did few repairs and service on it like, including replacement of top (intake manifold?) gasket.
had "reduced engine power" under hard acceleration.
with codes:
30FF: turbocharger , boost pressure too low
2AAF: Fuel pump, plausibly
found out the intake pipe? wasnt all the way in, that took care of 30FF code.


so now have these issues:

under hard acceleration over around 4-5k+ Service Engine Soon light comes up and engine runs rough,
after restart SES light goes away.

Current Error Codes Present:
29CE combustion misfires, cylinder 2 (goes away after restart )
2AAF Fuel pump, plausibly (goes away for some time after clearing codes)

about the 29CE, I found if thats the only code than to check spark plugs, coil packs, fuel injectors etc.
If I find a bad coil can i replace just one or have to replace all 6 ?

about 2AAF, found mixed results either HPFP, LPFP or fuel pump. are there 2 different fuel pumps or is hpfp the fuel pump thats in the fuel tank ?? very confusing.

any help greatly appreciated
