Rough idle no power

Rough idle no power
So the car idles a bit rough and then has no power when I try and drive. The Pcv and fuel filter were changed recently. The spark plugs look fine maybe the coils? I can hear the turbo spool when I drive. I clean mass air flow senors and it isn't throwing codes on obd. Any ideas?

What year? (you said maybe the coils - multiple coils would mean 99 or 2000)
If it's missfiring (runs rough/no power) it should set a code.
If it's idling rough you can try to figure out which cylinder it is by disconnecting the injectors one at a time, the cylinder with the least drop in idle speed will be the one missfiring. The automatic/constant idle system will try to correct the idle drop so you have to be quickly observant.
99 and 2000 have the throttle module that fails and causes all sorts of problems - how old is yours?
