Still Running Rough

After being told the O2 sensors were bad and taking care of oil leaks and such I was hoping the car wouldnt be running rough anymore. Sadly it still is. The guy at the shop said he called it smooth but to me after it heats up it is still running rough. Where the engine isnt idling smooth like at start up. The opti, wires and plugs were all also changed. Is there anything else that could be causing a rough run after the car is heated up? It has no codes but does eat some gas. Thanks for the advice.

Take a look at the spark plugs. Sometimes bad O2's lead to fouled plugs and the symptoms you describe...

The plugs were replaced with everything else. There are no exhaust leaks and there is no loss in power to lead me to believe the cats are clogged. If I rev the engine when its cold I still notice it popping at the cut out.
