Fast idle until idle control valve unpluged
1993f150 idle control valve replaced but still idles very high until I unplug the control valve. Is their a way to test the injectors to see if 1 or more are not working ? Any other fixes?

Have you checked for codes yet? A faulty TPS can also cause a high idle condition as well as other driveability issues. Might be worth the time to check the TPS with a meter. Use this for reference: Ford Fuel Injection » Throttle Position Sensor (TPS)
