Show me where the idle speed control is on the 1999 ford windstar

Check your vacuum line for the cruise module under the hood.

what code comes up when the engine light comes on

I had a recall on my speed sensor for Mercury, so make sure Ford won't fix it for free. don-ohio

code P0761-
Possible causes - Low transmission fluid level
- Dirty transmission fluid
- Faulty shift solenoid 3 valve
- Shift solenoid 3 valve harness or connectors
- Shift solenoid 3 valve circuit is open or shorted
P0761 FORD Description Shift solenoid valve 3 is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Gears will then be shifted to the optimum position. When is the code detected? The P0761 code is detected when the ECM has detected a mechanical fault with the solenoid energized, valve stuck off code O1744- is not a code these are the ones I have found that come close

replace VSS (speed sensor) and/or TRS (range sensor) use a DTC reader to confirm

on top of the air intake its a idle air control a valve that open to let air in the engine its stuck open start the windstar gently tap it the idle should go down if the rpm still high change the valve good luck pierre

it means the idle mixure is to lean, check or replace your idle speed control valve (ISC)

it could be bad plugs.stop up fuel filter.egr valve intake gasket leak or the idle speed control not working.

sounds like you may need to adjust the timing

You know, lookinig at this problem more, you have more possibilities of what may be wrong:

1. Your idle speed may be incorrect
2. Fuel filter may be clogged or water and impurities in your fuel system
3. Possible damaged coil pack or wires
4. Emissions sytem components faulty (a sensor, catalytic converter, muffler, etc.)
5. Faulty or incorrect gapped spark plugs
6. A vacuum leak at the intake manifold or vacuum hoses (check the hoses for cracks or damage)
7. Fuel injection or engine control systems malfunction (ECM)

This should keep you busy....at least with the easy stuff to inspect.
