I've noticed lately that my A/C has been quite warm when idling or in traffic, and blows nice a cold on the highway. I figure i need to pick up a 134s recharge kit, but haven't found the time yet. I just came back from my lunch break and I noticed the car, 99 accord 4cyl coupe, feels very sluggish and the exhaust is quite louder, like it's under a large load. And the A/C is even hotter. Could the A/C system just be straining the motor to pump cold air?
