low revs
 

got my clutch put in 2 days ago and had to get a new flywheel, now when i rev it over 1500rpm when it drops back down it nearly stalls then picks back up, does the same even when driving putting my foot on the clutch and changing up gears... what could be causing this? its got me stumped... its in an rs liberty

remove and clean the idle valve out. with throttle body/carby cleaner.
