Check ccvs and those vacuum hoses
Hey SFbay thanks for the reply
I went and checked them and they appear just the same as when I installed them a few months ago. bought both sides from bmw of newport (they are updated versions my old ones had round nozzles and the new ones are more squared) edit: also replaced crankcase vent hoses with the updated ones
As far as the vacuum hoses; I replaced the hose going from the front of the vacuum pump (the skinny hose) and i replaced the hose that is connected to the elbow boot after the MAF (another skinny hose); both when I replaced the alternator/generator not too long ago also as the old ones were rotted and had visible cracks and holes in them. i checked them as well but they appear to be as new as when i put them on
