1990 caddy deville. After warm and running for a while car stalls when coming to a stop

What is your question?

After it kills it is hard to start and if it does start it run with a lack of power until the RPMs are increased. Had a camshaft position sensor code and that was replaced which helped the engine run better but still problem persists. When the sensor was replaced the code ECM Memory Reset..

What makes this problem better or worse?

Problem after warm up

How long has your 1990 Cadillac DeVille had this problem?

couple of days, was running good before that
