Question
My Cadillac Deville Concourse was reving really weird. Then the battery totally died... I got codes for an ERG Valve and I think a torque sensor??? I thought that I would be the alternator, fuel pump or a sensor issue like the diagnostic said. Problems started when I stopped putting premium in it.

Answer
I need the YEAR and MODEL of the vehicle.

You may have gotten a mixture of gas and water from your local gas station if this fault occured soon after putting gas in the fuel tank or if you only have 1/4 of a tank left or are near empty.

Try adding 2 cans of DRY GAS or similar product to break up the possible water in the gas tank and fill the gas tank with gas from some other gas station.

Charge the battery and see if it will start.

Let me know.
