chek engine light comes on and car stalls on 1997 Chrysler Concorde

Check engine light comes on. Car has staled several times when at a stop sign and seems to be running rough at times. The sensor was just replaced and it is till doing it. I also had a new fan put in.
What do you think the problem may be and if is the computer how much does that cost to have it repaired.
