Okay so when it is cold is runs good and when it warms up it runs rough? If that is the case I would suspect a bad O2 sensor.

Always, check for codes first.

Could be a weak fuel pump...

o2 sensor .driver side under the header ! first give her a overall service ! check timing , fuel pressure , bad cat ? , fuel spray ( no drops ) , bad egr valve , dirty iac, vacuum leaks,replace the fuel and air filters
