  • no power uphill

    I have a 2000 firebird I just had the wires and plugs changed due to the engine missing. It ran fine a couple weeks but now when I go uphill it seems to lose all power and I have to press the gas pedal to the floor to get up the hill. any ideas whats causing this? I am almost ready to seel the car
