Since you seem to be a DIY, and you will probably need in the
future, I recommend a repair manual for year, make and model.
Most Auto parts stores carry. Or try filepeep.com if they have it, or try manualslib.com
Or possibly MFG website, or their customer service email.

How to fix fault code P1507


Possible causes
- Faulty Idle Air Control (IAC) valve
- Idle Air Control (IAC) valve harness is open or shorted
- Idle Air Control (IAC) valve circuit poor electrical connection
What does this mean? Tech notes
The P1507 code means that the engine idle is out of factory specification. Sometimes the Idle Air Control (IAC) may have carbon built up. Disconnect the car battery, remove the valve, clean, re-install valve, and drive the vehicle for about 5 minutes with the headlights and A/C ON to get the idle relearned.
If the problem persist, the IAC valve may need to be replaced.

How to clean the throttle body and the idle air control valve


I typically remove them to clean but they can be cleaned on the car. Get throttle body cleaner from the store and spray all over. Manually open the butterfly valve and wipe after. I would take the idle air control vavle off to clean it.

Diagnostics test says idle air control underspeed error? how do i fix 1999 ford explorer


change the idle air control valve.

Idle Air Control (IAC) Valve OPERATION The Idle Air Control (IAC) valve controls the engine idle speed and dashpot functions. The valve is located on the side of the throttle body. This valve allows air, determined by the Powertrain Control Module (PCM) and controlled by a duty cycle signal, to bypass the throttle plate in order to maintain the proper idle speed. Fig. 1: Typical Idle Air Control (IAC) valve which is mounted to the throttle body - cutaway view shows air bypass direction 89684g16.gif
--- REMOVAL & INSTALLATION
  1. Disconnect the negative battery cable. To remove the IAC valve, first disconnect the negative battery cable, then the IAC wire harness plug 89684p03.jpg
    Next, remove the two IAC valve attaching bolts . . . 89684p04.jpg
    . . . and pull the valve from the intake manifold 89684p05.jpg

  2. Disengage the wiring harness connector from the IAC valve.
  3. Remove the two retaining screws, then remove the IAC valve and discard the old gasket. To install: When installing the valve, always discard the old gasket and install it using a new one 89684p06.jpg

  4. Clean the IAC valve mounting surface on the throttle body of old gasket material.
  5. Using a new gasket, position the IAC valve on the throttle body. Install and tighten the retaining screws to 71-106 inch lbs. (8-12 Nm).
  6. Attach the wiring harness connector to the IAC valve.
  7. Connect the negative battery cable.

After sitting, hard to start, seems not to be getting fuel. you can spray starting fluid and it starts, must run at higher than normal idle for a few minutes, then will idle normally.


OPERATION The Idle Air Control (IAC) valve controls the engine idle speed and dashpot functions. The valve is located on the throttle body on. This valve allows air to bypass the throttle plate. The amount of air is determined by the Powertrain Control Module (PCM) and controlled by a duty cycle signal. Fig. 1: Cleanable IAC valve — 5.0L engine version shown, others similar 88484g22.gif
Fig. 2: Non-cleanable IAC valve — 5.0L engine version shown, others similar 88484g23.gif
prev.gif next.gif TESTING OBD-I System
  1. Make sure the ignition key is OFF.
  2. Disconnect the air control valve.
  3. Use an ohmmeter to measure the resistance between the terminals of the valve solenoid. NOTE: Due to the diode in the solenoid, place the ohmmeter positive lead on the VPWR pin and the negative lead on the ISC pin.
  4. If the resistance is not 7–13 ohms, replace the air control valve.

How do i remove and clean the IAC


Operation

The Idle Air Control (IAC) valve adjusts the engine idle speed. The valve is located on the side of the throttle body. The valve is controlled by a duty cycle signal from the PCM and allows air to bypass the throttle plate in order to maintain the proper idle speed. Do NOT attempt to clean the IAC valve. Carburetor tune-up cleaners or any type of solvent cleaners will damage the internal components of the valve.

Removal & Installation

  1. Disconnect the negative battery cable.
  2. Detach the IAC solenoid connector.
  3. Remove the two retaining bolts and remove the IAC solenoid and gasket from the throttle body.

My RPM is always at 3000


it sounds like you have a stuck IAC, Idle Air Control Valve. It meters air in when the throttle plate is colosed (foot off gas).

Autozone can scan for fault codes for free.

May just need cleaning. Try that first.
