Your car and all OBD2 cars from approximately 1996 have a common 16 pin diagnostic socket under the dash board of your car. There are many scan tools on the market that read the diagnostic trouble codes stored in the on board computer.in your car some are better than others.
Your observation about the air conditioning may be normal ac compressor operation. The compressor engages and disengages when the air conditioning is working and it does put a load on the engine each time, but the idle air control should bump up the idle speed when the air conditioning is on.
If you have a Check Engine Light/Service Engine Soon Light it may store a code for a problem with the idle control system. Please let us know the out come.

Yes they do and it's free. Also if they do not carry the part, they will refer you to Pep Boys who have a large inventory of parts for cars.
If you live in the Philadelphia area, I know of a mechanic who will assist you and don't worry. He doesn't charge an arm, leg and/or thigh.
