What else could cause engine to cut out run rough, idle jumping up & down?

Had tune up, replaced ignition coil, new platinum sparkplubs, engine still cutting out/running rough, sometimes hesitates when press accelerator, runs worse when air conditioner is on. Also ran fuel system cleaner thru tank of gas.

  Sounds like a misfire
  
  Sure the spark plug wires are new,and connected good?
  ....maybe bad fuel injector....?

  My car was doing that and they changed the fuel sensor and a new air filter and solved the problem

  Hook up a code reader to the diagnostic connector under the dashboard on the driver side. This is the way vehicles are diagnosed. The codes will lead to the repair necessary. The cost of the tool is not that much considering that a shop will bill you a similar amount PLUS parts and labor to fix the problem. There are instructions that come with it and it is easy to do. After you read the code or codes, write them down and repost with the codes and we can tell you what parts to buy to DIY if you are up to it. http://www.autopartswarehouse.com/.../E203030.html
