Not much info. Idle is controlled by the IAC. Maybe it's bad. I've also seen a faulty (low temp) coolant temp sensor cause odd idle (car thinks it's -34 degrees out and tries to compensate). Vacuum leak around the intake can cause odd idling. But the list goes on and on. Fuel pressure, injectors, etc. Good luck.

Leak in the intake tract will cause a fluctuating idle
