more than likely its the timing chain it might have to be reset which if u dont go to a mechanic that u know and trust it can get pretty pricey

It's not the timing chain... What engine do you have? It's probably the IAC, idle air control valve... it's either damaged or dirty. You can clean it relatively easily, just don't move the plunger when handling it
