Sounds like u might have a vaccuum leak I would try looking the the s shaped hose going to the pcv they colasp and leak vaccuum also spray carb spray around everywhere it could leak vaccuum if the rpms go up or down or the engine stumbles misses or dies u have a leak there I would also check around the number 1 and 2 intake port where the intake gasket goes they they leak there too it's by the power steering pump look there u can actually see the gasket wrinkled up.also check for codes let me know what u find.
