My 1994 STS drives fine on flat roads but loses power severely when going up any hills. It has new plugs and wires and the mechanic says he cleaned the fuel filter but he never put the car on a lift and I understand that the fuel filter is under the car in the rear. I need this car to run for me. Can anyone help?

Yes, could be the fuel filter, or fuel pump, or even the coil. You are in the wrong forum. You will get more help in the correct forum, as those folks will be mor familiar with your vehicle.

If the codes don't indicate ignition, check fuel pressure.
