What driveability issues are you getting?

The outside temp sensor is located in front of the AC condenser below the hood latch, they probably did not reconnect the wires to it, take a look and see if the connector is off.

The right left bank fueling difference could be related to a vacuum leak or injector issues.

Try disconnecting the battery and let it go through a re-learn with regard to the closed throttle angle. You might need to clean your throttle body if it is hanging open or your TPS is out of adjustment

the car rides great i only get 7-10 miles a gallon lately but other wise it drives excellent

Let the engine idle cold and warmed up and look at the exhaust. My guess is that you will see black smoke, indicative of a rich mixture.

Check your air filter for restriction

Ideally, you should lift your fuel rail, so you can see the tips, and turn the key to the ON position to pressurize the fuel system (NOT TO START POSITION) and see if you have any dripping injectors.

Try disconnecting your battery and doing a relearn.

Take your air cleaner off and see if your throttle plate is being held open with dirt, check the two tubes that look up under the throttle plate while you are there.
