Idle control where is the idle control valve located on my 1995 ford taurus. it is idle to fast

you might have to have the programing checked and possiblly adjusted

The code is for the idle air control valve which controls idle speed.
The problem could be a faulty control valve, or a vac leak which is letting in air to the intake and bypassing the control valve.

Replace the idle valve with a factory one and remove the negative battery negative cable for 5 minutes to reset the idle control system to base line settings.

this is normal, if the idle wasn't high (about 2,500 RPM) the engine wopuld stall out until it warms up to normal temperature. If it is above 3000 RPM for more than a few seconds you have a problem.

may just need cleaning with carb cleaner.

here is 1996, oldest I have:

Section 03-14: Engine Controls, Electronic 1996 Taurus, Sable Workshop Manual
REMOVAL AND INSTALLATION Idle Air Control (IAC) Valve Removal

1. Disconnect battery ground cable (14301). Refer to Section 14-01 .
   

1. Disconnect the engine control sensor wiring (12A581) from the idle air control valve (IAC valve) (9F715) at the idle air control valve electrical connector.
   

1. Remove the two idle air control valve retaining bolts.
   

1. Remove the idle air control valve and idle air control valve gasket.
   

Installation

1. NOTE: If scraping is necessary, be careful not to damage idle air control valve gasket surfaces, or drop material into intake manifold (9424) or throttle body (9E926) (depending upon application).
   
   Clean idle air control valve gasket mating surfaces.
   

1. To install idle air control valve, reverse Removal procedure.
   

1. Tighten the idle air control valve retaining bolts to 8-12 Nm (71-106 lb-in).

1996 EXPLORER This TSB article is being republished in its entirety to include the 1995 4.6L Thunderbird/Cougar. ISSUE: After a 1-4 hour engine soak time, long crank times and/or long crank to start followed by a stall may occur on some vehicles. No further stalling or rough idle will occur after the engine is running. The long crank and/or stall may be due to the Idle Air Control (IAC) Valve sticking.
ACTION: Replace the IAC Valve with a revised IAC Valve if no Diagnostic Trouble Codes (DTCs) are present. Refer to the following Service Procedure for details.
SERVICE PROCEDURE

1. Perform normal diagnostics and correct any DTCs as required by referring to the appropriate year Powertrain Control/Emissions Diagnosis (PC/ED) Service Manual.
2. If no codes are present, replace the IAC Valve by referring to the appropriate model/year Service Manual, Section 03-14. Refer to the following Idle Air Control Valve Application Chart for proper IAC usage.

A code P0174 may mean that one or more of the following has happened:

• The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
• There could be a vacuum leak downstream of the MAF sensor. and your solutions are.
  • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner . Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
  • Inspect all vacuum and PCV hoses, replace if necessary
  • Check for a dirty fuel filter and proper fuel pressure

That isn't alot to go by but you may have a broken throttle return spring, sticking throttle cable, a TPS(that is out of range), a vacuum leak, a defective IAC valve(idle air control valve) and/or maybe the engine light is on. If so have it scanned for codes. Good luck.

several things can do this but most likely would be
1 TPS trottle postion sensor = replace
2 stuck butterfly valve inside the trottle body = clean out with trottle body cleaner try to get most of the black build up with a old tooth brush
3 bad trottle cable= feel the cable make sure it moves freely if not replace it

The IAC valve is usually the problem with the 1.9 Escorts ,causing a very poor engine idle at a stop. It is located on the side of the throttle body .
