Yes, the 2000 has the Magnetti Marelli ignition, opposed to the Delphi system for 2002 and later. Here are a list of causes for your problem.
1. Intake manifold leak ( usually associate with the spark plugs being a very white color)
2. Fuel pressure ( needs to be 40 to 45 pounds at idle)
3. Throttle position sensor ( can be out of range or have a voltage dead spot in it like the
one I repaired for a customer last week)
4 After market fuel controller ( like a power commander etc, could be the problem)
5. Water in the gas
