I have a 1999 Pontiac Grand Prix with 98,000. I have
white smoke coming from the mufflers, and a code reading of 201. I replace the fuel injectors with acel.
17lb\hr, it still did it. I have replace the oxygen sensors, the coil, the fuel filter, and the spark plugs.
I still have white smoke coming from the car.

Is it smoke or water vapour? You may have a coolant leak into your cylinders, which would create large white clouds of vapour from your tailpipe, and would indicate a failing head gasket. Check your coolant level - it's a sure indicator.
