There is a way of slightly changing the idle on your Taurus. I will tell you, but first you may want to test the seams of the intake manifold gasket. When you get a leak around the intake, or the Airhorn on top of it; the effect is the same as opening the Throttle and letting more air into the engine. This may be the reason the engine is running faster now.

Test your seams with a spray water bottle while the engine is running. If you have the engine stall or lose RPM you have found the leak. Fix it and the engine will run slower at idle.

The other way to lower RPM is an adjustment to the TPS. There is a slot on one end of the sensor. The Throttle Position Sensor is mounted on the Airhorn, has 2 screws and 1 Electric connector. It is about the size of a Butane lighter. If you can't get adjustment there, on the opposite side of the Airhorn from the TPS is linkage. There is an odd looking set screw where the linkage rests. It is made to be difficult to turn, but it will change the RPM.

High idle 2003 dodge ram 1500 changed the TPS it helped a little, reset the ECM that helped a little more. still idles high till it warms up then occasional high idle should i change the IACM?

It is normal for vehicles to idle high until warm up.
First thing I would do is scan the vehicle for codes.
Otherwise you will be changing things until the end of days. It could be a vacuum leak, maf sensor, air filter, spark plug, battery cables/voltage.

Idle air control motor. Mounted to the side of the throttle body. Pull it, clean it and the hole it came out of. Brake clean and a tooth brush. If it still idles high, replace the motor.

High idle and running a little rough, sluggish in 2006 sequoia

Check the throttle body and see if it has build up around the butterfly. If so, clean the butterfly with throttle body cleaner. This may be it. There are other possibilities but this is a simple inspection.

Honda civic 2000- idle speed is high even in park or neutral

Check your coolant level. The Idle air control valve works with coolant in the system and will produce high idle it there is very little coolant. Also check to see if there are any vacuum lines disconnected. They can also cause the high idle.

Myservice engine light came today rogh in idle at light rpms seem a little high this is a 98 saturn sl2 I think engine is a 1.9

the check engine light means that a code has been set. the code will reference a faulty system that must be diagnosed and repaired. sorry for the vagueness, but there are e gads of codes that can cause the rough idling

most aftermarket parts places will scan the car for free. this will give you an idea of where to start.

2004 crvautomatic high idle on cold startup 1600rpm takes 3 to 5

Hondas are famous for this, my accord does it. This is normal UNLESS it still idles high after normal running temp. has occured. Watch your temp. gauge when it reaches normal temp tap the gas a little bit if the idle drops then it is fine
