Question about Ford Explorer Sport

1 Answer

Occassionally when I start my 99 Ford Explorer it'll die when I take foot off accelerator. I was told that I need to replace IAC motor. Any advice? Does this sound like typical "symptom" for IAC replacement?

It could. Be sure to clean the throttle body first. Open it wide open and take an old toothbrush and carb cleaner and make sure its clean. Usually when the IAC is bad, when you firsty start the truck the idle speed will "flare" to like 12-1500 rpm, then settle down to 7-800. If it doesnt do that, then it could be bad.

I would check to see if the intake gaskets are leaking, Especially the upper or plenum gaskets.

03 ford explorer starts and dies


First, this "solution" assumes that the engine starts and runs OK, but will not idle once the key is returned to the RUN position.

A real common cause of that is the Idle Air Control Solenoid (IAC). To see if this is the problem, see if you can keep it running by stepping on the accelerator a little right when it is starting.

NOTE: you don't want to step on it before you start cranking the engine over or you will flood the engine. Also, step lightly, just enough to see if you can keep it "idling".

If you can keep the engine idling this way, then replace the IAC.

If this does not work, try unplugging the MAP Sensor and see if it will start and idle. If it continues to run (idle) with the MAP sensor unplugged, then replace the MAP sensor.

The next thing to suspect if none of the above works is the ignition switch. If it gets this far, post a comment to let me know and I'll post some instructions for testing the circuits for your ignition switch.

My 99 ford explorer cuts out and dies when accelerating in drive


You may have dirty or clogged fuel injectors, may also be problems with the ignition system. Might also check the fuel pressure to make sure the fuel pump is working correctly.

My explorer starts but then when foot is off gas it just dies


Clean or replace the IAC-idle air control. It is on the intake, controls the idle!

What would cause an 04 f-150 to die after start up and not refire?


Try cranking the truck with your foot on the accelerator pedal. Just crack the throttle open a little and try to start. If the truck starts then dies when you take your foot off the accelerator, you have a bad, what is called an IAC valve. It is what controls the Idle Air bypassing the throttle.

Check for dirty throttle body. Maybe IAC motor gummed up. If throttle body dirty, get some carb cleaner and a soft toothbrush and clean well. If this doesn't work, most likely an IAC (idle air control) motor.

Dies when drive


My 99 Explorer would not run unless you held the pedal to the floor. Found out ford has a recall on their intake gaskets. If you see what the intake gaskets look like you'll wonder how the motor runs at all. I had that prob for 50,000 miles and I changed those gaskets and now it runs like a new ford.
