Engine loss of power after driving through a puddle?

1993 Plymouth Acclaim mileage: 159,000. I was driving home and it was wet out, I drove through a puddle and shortly after my car stalled. I continued to drive and every time I stopped at a stoplight or I had to come to a stop, I could feel the car begin to pull/chug. Now it seems to be happening when I am driving no matter the weather conditions. It hasn't stalled since. I can just feel when I accelerate sometimes it not wanting to go like it should.
