Hi Im David, thanks for visiting the site. on a 4 cylinder vehicle, the ac compressor adds so much extra load on the engine that it is very noticeable. if the vehicle is in need of anything like new plugs, a new drive belt, or a new harmonic balancer then it would explain these symptoms. my suggestion would be to remove the belts and turn each pulley by hand to make sure none of them are binding or frozen. it all is ok there, i would recommend a good tune up.
