my 2000 taurus just started blowing black smoke and can hardly drive with the engine running really bad. i changed fuel pressure sensor , coolant temp sensor , MAF sensor, tps and ics sensors , the black smoke died down but it wont rev up while driving . does anyone know what could be causing this.

Black smoke = running EXTREMELY rich.

I assume the CEL is on? Even if it isnt on now it will be on soon. If it doesnt come on either it is burned out or some PO removed it.

Stop throwing random parts at it hoping to fix it. The first step is to retrieve all codes stored in the PCM. A decent scan tool that can read and graph PIDs will likely come in handy troubleshooting the issues.

Injector stuck open and spraying fuel into the engine? - there's an excellent YT vid on this issue on South Main Auto
