Ok...I looked up what people were saying about rough idles and how to fix them. My mustang has had full tune ups, spark plugs changed...the works. So far the forums have come down to an 02 sensor change...well, mines fairly new so I'm guessing, unless it's faulty, it has to be something other than the O2 sensor?

Anyone have any ideas for something else that might need replacing?

Thanks.

Well it could be a few things; Idle Air Control Valve, Throttle Position Sensor, worn out PCV Valve. Have the IAC and TPS checked for functionality.
