Question about 2000 Ford Taurus
The check engine light came on flashing. I disconnected the battery & reconnected it. The check engine light stays off but it has rough idle and was cutting out at high speeds.
It could be the O2 sensor. Connect the diagnosis tool and check the codes to better understand the problem.

Check and see if the EGR valve is leaking, to check this spray water on it at idle, if the water steams off the valve is leaking and is the source of your problem, also are you sure you hooked the new DPFE sensor up right? re-check it..

IT SOUNDS LIKE THE IAC (IDLE AIR CONTROL) MOTOR IS BAD OR GOING BAD, BUT THE QUICK SOLUTION IS GO TO ANY AUTO ZONE,OR ADVANCE AUTO PARTS STORE, AND THEY WILL CHECK IT FOR FREE,& TELL YOU WHAT SIGNAL CODE MADE THE CHECK ENGINE LIGHT COME ON, I WOULD DO THAT JUST TO BE FOR SURE, BECAUSE THERE ARE A FEW OTHER THINGS THAT CAN CAUSE IT AS WELL,SUCH AS MAF SENSOR DIRTY,OXY SENSOR GETTING A BAD READING,ETC.

Engine stall or RPM fluctuates
This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control
