my idle hunts around 1500-2000 rpm. it has never done this before (i took the car for a drive earlier and idle and everything was running fine). wondering what could be causing it.
took the car out for a short stroll and hit full boost (a little bit about 1 bar) and then after the idle started acting up once i push the clutch in or have the car in neutral. was wondering if maybe a sensor or vacuum hose got loose somehow?
took a brief look around the engine bay and didnt seem like anything got loose.

some specs on the car:
s13 sr20 blacktop
has pfc

i also just recently changed the water pump if that could be related. and also messed around with the apexi auto timer if that could possibly change anything?
