hey just replaced my valve cover gasket today, install was smooth, while i was there i decided to also do a compression test, i got about 180-190psi on all cylinders, but now i have this weird rev at idle, took it for a good spin, came home and let it idle for turbo to cool. and it would idle normal at 800 then every 15-20 seconds rev to 1000 for a second and back to 800, it repeats this inf. amount of times.

now, when moving spark plugs i dropped 2 of them twice... and my secondary air pump is shot, makes the loud winding noise at cold start up for a few minutes then stops, (also would the SAP delete be worth my time?)

vag-com says normal faults, oxygen sensors

any help would be great, thanks!
