The engine runs rough at a idle done gave it a tune-up and it still does. What can be the problem?

I suspect a mapp sensor, or intake air temperature sensor, and idle air control valve. However, we need to narrow that down rather than assume possibilites, so what you should do is bring it to autozone or your local parts place and get a computer scan done, they are free. Jot down the trouble code or codes and bring them to me so I can pinpoint your problem
