Does the check engine light come on at all? If yes then pull then code(s). If no codes check all the connections under the hood and check the grounds too. Also have the charging system checked out. A weak charging system or battery can cause low voltage and make the car run bad when an extra load is added (like the A/C).
Another good idea would be to replace the fuel filter if it hasnt been replaced in a long time. Many times i have seen cars run bad with no real cause and found that a semi bad fuel filter to be the problem.
