on the A/C...? and the car runs normal when it's off. And it when I run the A/C while in park, the engine's power fluctuates up and down almost like it's going to stall. What does this sound like? The last time I had it serviced I had to put in a new radiator and the repairman told me to keep an eye on my water pump. Could the water pump going bad cause this? The car has almost 150,000 miles on it so I don't want to spend more than the car is really worth, but right now I also can't afford a new one either.
