Just spent $2100 for a tune up becasue they had to replace 3 Coil Packs and the spark plug wires with the spark plugs. No codes prior to the tune up. Went 30 miles in the car and now all of a sudden it is pulling both of these codes. P0170 Fuel Trim ( Bank 1 ) & P0110 Intake Air Temperature Sensor 1 Circuit. What the heck happened?

The first thing I would do is to check all intake and vaccume hoses for leaks and breaks. These will cause these codes. If they are fine then check the voltage to the air mass sensor. There are one ground(brown wire), one 5 volt wire, one 12 volt wire, and one single wire. Any good digital volt meter will work. If the voltages are fine, then I would change the sensor.
