Obviously it s shortage of gas supply to the engine that causes it. Increase the slow running/idling speed.

Hi thats sounds like an air fault
check all the air pipes for leaks make sure they are not taking in to much air and choking the engine.

Also check the air mass sensor, and clean it with carb cleaner. make sure to look on the under side of the air pipes and around each seal.

Hope this helps
Regards
Dan

My 2005 Ford Focus won't stay running unless my foot is on the gas. It starts just fine & the check engine light is NOT on. What could be causing this?


It is likely that the engine management system has lost its base line calibration. If the battery is weak and during the crank to start the voltage dipped low enough the Engine Control Module lost its calibration. If the pedal is depressed during the crank the TPS (Throttle position sensor) will lose the idle position for the throttle. The hunting and surging and resultant stalling is the ECM seeking out the limits and re-establishing the throttle idle plate location.

If battery is OK than running the car allowing the calibration of the vehicle to reestablish itself will correct the problem. My experience is that this happens if the gas pedal is depressed during crank with a very very low battery voltage. Always the best way is to not touch the pedal during any cranking starting procedure. Or after a battery replacement.

To accelerate the calibration process attempt to run the car ingear tring not to allow the car to stall. After afew munites the car will have reestablished its normal running calibration and you will be allset.

Car stalls when foot off gas pedel does not hold idle


these trucks are equipped with an idle speed control motor. What you're describing sounds like that part has stopped working. The part is designed to maintain idle when gas pedal is released. Now if you hear an audible hissing noise under the hood, then theres a vacuum leak which can cause the same problem, but it sounds like the idle control motor. Good luck.

1999 ford explorer starts, but will not stay started unless foot on gas pedal


SOUNDS LIKE THE IDLE IS TOO LOW! YOU MAY NEED TO IDLE IT UP JUST A LITTLE! YOU CAN EASILY DO THIS AT THE THROTTLE PLATE UNDER THE HOOD! THERE IS A SMALL BOLT, OR SCREW LOCATED ON THE BACK SIDE OF THAT PLATE! TURN IT CLOCKWISE, AND IT WILL RAISE THE IDLE!

Starting issues


Had the same problem on our '99 Explorer.It turned out the battery was on it's way out, and without keeping a foot on the gas for awhile, the thing would die as it appeared that too much of the charge was going into trying to charge the battery, leaving not enough to supply the ignition at an idle. It would run once it warmed up a bit, but a new battery cured the problem.
