P0153 error code for 2000 Ford Taurus SES V6 3.0L

What does it say for that code? What sensor was replaced? Still showing what?

The code P0153 is for O2 sensor with slow responce on bank 21. This will not make your car idle fast. You have either an IAC problem or unmetered air. You should take your car to the dealership. They can pin point the fault and tell you exactly what is wrong with your car. Then the dealership can stand behind thier repair. There are many things that can cause your car to idle fast. So before you waste your time and money on people's guess... just pay to have it diagnosed by a profesional. (dealership)

Please go to this page for engine misfire causes.

You need the engine control computer scanned by a dealer for faults, this is absolutely essential to figure out what is wrong here.

You will need to put your car on a diagnostic fault code reader. The engine malfunction light will come on if there is a fault with the emissions if it runs ok and isn't misfiring it's probably a oxygen sensor fault or a catalyst fault. The light won't go out unless the fault is cleared

I assume you are saying you have a check engine light illuminated.

Most auto parts stores will read the OBD II code(s) for check engine lights at no charge. The codes they read will give you an idea of what the problem is.

sounds like a maf issue was it new?171/4 is usually uim vac leak

well that would lead me to believe that your crank position sensor is going bad, and it will not show up on a computer scan for fault codes, I would have it checked along with cam sensor and replaced if necessary, before you get left somewhere desolate and the car wont start even after the sensor cools down
