PONTIAC BONNEVILLE GAS PROBLEM

2001 Pontiac Bonneville • 150,000 miles

Transmission and engine are good. Spark plugs are good. All wires have been checked. Fuel pump and filter are good. Fuel injectors good. Yet when step on gas to accelerate car acts like its not getting the gas so wont go. Runs fine on flat surfaces. Computer code says cylinder one misfiring. Cant seem to find problem

Scan for codes and check fuel pressure, low pressure will cause misfire
