My clutch is soft in my 2000 ford focus . It won't

The idle speed is controlled by the PCM based upon sensor inputs using the Idle Air Control (IAC) valve to regulate air input past the closed throttle plate to the intake.
The PCM controls the IAC using a solenoid to move the valve body that opens and closes the air passage to the intake. The PCM ensures a seamless transition from IAC control to throttle plate control of engine speed using the Throttle Position Sensor (TPS) attached to the throttle plate.
If you pull the electrical connection from the IAC (round body fitting bolted to throttle body) usually the engine will stall. If it doesn't then you may have a vacuum leak. Check hoses and connections are secure. Your symptoms are consistent with a small vacuum leak.

Try holding the idle a bit longer, then the PCM will set a code. So that is what you need to do, try to hold the throttle just off idle to retain the hesitation long enough for the PCM to try a few strategies and settle on the problem and set the code. You can then get the code read at Autozone, Pep Boys or Checker. You need the P0123 number not the description.

Hope that helps!

Set your idle speed to mfg recomindation if that doesnt help check the dash pot that is what keeps the engine from stalling at sudden speed reduction

Try replacing your Engine Coolant Temp Sensor, it's cheap and easy to replace. Just remember do it when the coolant is cool to work with before you start cracking a pressurized system.

Sounds like it is a clutch issue. Have the clutch plate checked or check the clutch and friction plates. I know it sounds strange but In reality we always press teh clutch all teh way in to shift. But going from 2nd to third you actually don't have to. Going from 3rd to 4th is even less of a distance. It may be a problem between the clutch and friction plates depending on when you last had them changed and adjusted.

your fuel filter might be old and clogged. try replacing it. if it is and not enough fuel can get through, the engine will stall when you let more air in (step on the gas pedal).
