Did you replace the O2 sensor that bolts into the catalytic converter, or on the exhaust manifold?

Stop by a parts store and have them read your codes. You connector is behind the ash tray.

The code will start with the letter P and have four numbers, like p1234. Post the actual code on here.

What was the error code from your check-engine light?

Yes, get the codes.

Sometimes,,,,and idle going up and down has more to do with the IAC being dirty, air in the coolant or too much air in the cooling system.

The IAT sensor is on the upper part of the intake manifold on the driver's side of the engine. It has a two or maybe three wire connector going to it. It will unbolt from the intake manifold just like a coolant temperature sensor.
