I have a ford taurus with 152,000 miles and this car had been very good to us until now I recently had to replace bank 2 oxygen sensor, and that took care of the ceck engine light, but some times my car after driveing home from work when I start to slow down coming into town it runs a high idle about 1200 to 1400 rpms, and at a take off from a stop it starts to chug is it my idle air vavle or my throttle vavle sensor, its really not snappy on the take off either. It also idle very rough at low idle. I checked the ecm and have no codes?

It's hard to diagnose without the computer setting a trouble code. The first thing I would check is your vacuum lines. Make sure there are no cracks or leaks and all lines are on securely. If that's OK, it could be your Mass Air Flow Sensor. They get contaminated where they don't work right, but not enough to set a trouble code. As you stated, it could be the Idle Air Control Valve or Throttle Position Sensor. Those could be checked with a digital multimeter. Check the vacuum lines first and post back if you would like to check the sensors.
