MAF (Mass Air FLow) sensor measures the exact amount of air entering the engine and delivers fuel accordingly. If dirty, it responds with a lag that can induce oscillations. Dirty MAF can occur if car operated without or with damaged air filter. EGR valve recirculates exhaust gazes for more burning. Not a probable issue here but disconnecting it as suggested will clear that option.
