No, not the TPS. It may be a vacuum leak or a stuck EGR or purge valve. Please see my tip at http://www.fixya.com/cars/r7427423-fix_poor_idle_high_idle_stalling_fuel . These are generic instructions.
I will send you specific instructions for your Taurus.

    Here is the EGR valve. Take it off and see if you can blow thru it. If you can, it's stuck open. Clean it to see if it will close better.

    Here is your purge valve. Make sure it doesn't have charcoal leaking from the cannister and blocking the valve open.

Over revving


I had similar problem on 98 Taurus. The plastic housing from air filter to Throttle body had crack on bottom, could not see from above...car would over rev sometimes, then almost stall, Replaced it, with good one from junkyard. Runs smooth again. Crack came from shoving that housing out of way from putting in new thermostat earlier.

2001 FORD TAURUS IDLES BAD


i recently had this issue with my 2001 taurus dohc engine. when you drive it seems that everything is fine. when you stop, the car will idle very low and somethimes shut off. there is a hose under the throttle body that is attached to the pcv valve. over time, this hose will collapse and eign to tear. i replace that hose (autozone for $10) and it solved my idling problem.

Car stalls after warm on hot day after a few stops. will stall when stopping at intersections, and when taking foot off the gas going down hills.


The idling setting in the car is not set correctly or the idling is LOW due to fault in the setting.
You will need to check if the throttle position is correct and the idle setting WITH THE CLUTCH PRESSED must be of the CORRECT IDLING RPM. If not reset the position after cleaning the system.

2001 Ford Taurus idels low and stalls sometimes when stopping at a stop light


sometime this will happen if the throttle blade idle hole gets plugged with carbon. if you take off the air inlet tube off the throttle body and look into the throttle body you will see a round looking flat disk , you will see a small hole in it .about the size of a stir stick straw .this hole gets plugged with carbon and will effect the idle.it calibrated to let the right amount of air in the engine @ idle.if you clean this there is a good chance this will fix your problem . be careful what cleaner you use as some of the throttle blades are coated with a Teflon coating(local parts store will have the proper throttle body cleaner for these ford throttle bodies )

95 taurus idling too high like it is stuck wide open


Several issues can cause this problem, either singularly or in combination.. Check the throttle body for dirt and sticky carbon deposits. clean the throttle body using a spray can carburettor/choke cleaner, and with the throttle valve held open, wipe out the bore of the throttle body with a solvent soaked clean rag. Make sure the throttle valve is not sticking any where in the throttle travel between closed and open.

Next, check the idle air bypass valve that is mounted on the top of the throttle body, for dirt and carbon deposits inside that can cause the idle air bypass valve to stick in an open position. Clean the inside of the idle air bypass valve with carb cleaner.

If the ignition timing is over advanced, (Specifies timing advanced is10 degrees Before Top Dead Center, with the in-line spark out plug removed from the spout connector housing, and with the idle speed set to the idle RPM shown on the emissions sticker under the hood, with the engine fully warmed up,) use a timing light to check and set the ignition timing to specification.

The throttle position sensor must be installed on the throttle body using the required method or the idle speed will likely be excessively high. Beginning with the battery negative cable disconnected from the battery, and with the throttle position sensor removed, place the sensor in position on the throttle body with the drive tabs on the sensor placed after the drive tabs on the throttle shaft, the holding the sensor on the throttle body, rotate the sensor counter clockwise to align the mounting screw holes in the sensor and the throttle body, Insert the sensor screws into the senor screw holes, into the threaded holes in the throttle body and tighten finger tight. Carefully center the sensor on the sensor screws, then tighten the screws firmly without over tightening. Reconnect the sensor electrical harness connector.

Inspect the throttle valve idle stop screw adjustment that holds the throttle valve open slightly, to prevent the throttle valve from touching the throttle body bore surface with the throttle closed, and the accelerator pedal unpressed.

98 explorer stalls sometimes when coming to stop. and acts like cutting out while driving


check the voltage to the THROTTLE POSITIONING SENSOR
that is usually the problem if its not holding at 1.5 volts
any other range it will die out when idling and sluggish or hesitating upon driving

1996 Ford Taurus power hesitation


If you disconnected the Mass air flow sensor the car should have die out at idle. Check fuel pump pressure at the fuel rail should be 30 psi at idle. Low fuel pressure will cause your po 171, 172, problems which could cause the other to problems. You might be needing a fuel pump and filter.
