You might need to change the fuel filter, Check your air filter also.

Check first if the fuel filter needs replacing. This may be an issue with the Idle Air Control Valve. But first check the vacuum hoses for leaks or loose connections. Your timing may also be wrong. If this was not checked a long time it is good to have this checked. Other than that you may need to have to spray carb cleaner into the intake manifold of the engine and the Idle Air control valve. If this does not solve it the IAC may need replacing.
If you can also have a scanner connected to the engine to see if there are error codes. Some error codes amy be stored in the computer box even if the check engine light is not on. It is a good idea to do this. Some shops would let you borrow their scanners.
