Have the computer scanned for codes, the codes will tell you what is not working correctly and then you will be on the right path in the diagnosing, you may have a bad idle air control valve or maybe a leaking fuel preasure regulator, start with the scanning.

Best thing to do is if you have a check engine light on is run a scan and see what codes come up..If no check lights on than could be your battery or a coroded battery cable,or both,,doent idle right? Should be a check engine light on,,,,,,Auto Zone parts will run a scan for free and tell whats wrong and read the codes for you.
