Hi so I’m having a problem with a 1999 Ford Explorer 4.0l v6. The car doesn’t want to turn on unless I go WOT but every time I let go of the throttle it turns off. Hope someone could give me some advise.

What happens if you lightly step on throttle while starting the engine, and keep it there once the engine starts?

If I step on it slightly after I turn it on, it stays on but if I let go completely it turns off

Have the throttle body cleaned along with the Idle Air Control valve.

If it still stalls after letting off the accelerator, replace the IAC valve.
