I would suspect the alternator. A low voltage will cause this with some electronic instrument clusters. Get a voltmeter and check to see that the voltage on the battery when the car is running is higher than when the car is not running. A good battery may indicate around 13 volts when fully charged, but while running an alternator will run higher voltage often greater than 14 volts. Be sure to bring the idle up while testing for running conditions.

In the gas tank take out the back seat there is a panel where the fuel pump is accessible.

a cylinder misfire is usually caused by bad spark plug or coil.

check the passenger side fuse panel inside the car there is a little cover that come off to get at the fuses. there is a fuse box outside on the fender passenger side and I think there might be one under the dash where the radio is.

sounds like a fuel problem check to see if it has an emergency fuel shut off valve. throw a little gas in your dash pot and if it starts then it is a fuel problem.also check you fuse panel under the hood passenger side there is a relay there for the fuel. I know cause I had a problem with it and i spent a lot of money before I figured out it was the relay. good luck

The Air Temperature Sensor is built into the Mass Air Flow Meter. It is located on the air intake tube, between the air filter box and the metal intake manifold, held on with 2 screws.

The Coolant Temp Sensor is located on the back side of the engine (closest to the firewall), closer to the driver side of the engine. It is close below the Csm Position Sensor, that is located on the cylinder head.

If you had problems with either, the DTC would be P-0115 for the CTS and P-0110 for the ATS.
Note that the ATS cannot be serviced alone, you would need to replace the MAF assembly.
