1995 Ford Escort Stalls when idleing and loses power in tur

My escort wagon stalls often when idling in park, neutral or when I pull up to a stop light. This has been going on for a year. I recently had the ac fixed, and it doesn't stall if I have the Ac on, but does if the ac is off, same as it has before. It also loses power, even with accelerator pressed to the floor when going around turns, like on an on ramp to the highway. I've changed the IAC, fuel filter, and cleaned the maf sensor.
Any help is appreciated!!
