Could be caused by one of the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it and keep testing.

Thanks very much for your help!I checked for any fuel leaks around filter or lines or tank & found none, I re-gapped my spark plugs,changed my plug wires that were loose, cleaned my battery posts well and changed both cable connections,then drove 10 miles to let computer reset,filled up with a good grade gas and drove back. Seems to be working much better. Thanks again for your help.
