Engine Stalling and/or Hesitation on Acceleration due to Faulty Idle Air Bypass Valve on Mercury Sable

If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.

Idle control valve makes the idle high and with foot off the accelerator car runs at 40-45 MPH. I disconnected the electrical plug to the valve and car runs great!

Car starts,but dies immediatley when take foot off gas. When pressing on gas, will die if I dont rev engine. Also, this summer electric locks stopped working and recently car seems to idle high when sitting or when I put heat on.

When the car is in drive, it jerks and hesitates while idling. If I put it in neutral, it's fine for the most part.
Having this similar rough idle problem. Was going to try and replace the idle air bypass valve but the auto parts suggested trying a fuel additive BG-44K. Well had good/not so good results. BG-44K within 20-30 miles of adding it to a full tank stop the rough idle but the rough idle returned. I'm going to try another treatment before replace the bypass valve. Found BG-44K a lot cheaper on ebay, this stuff is not cheap but I'm a believer of it. So bigger maintenance question is do our fuel ejectors get plugged up from cheap gas / ethanol and such???

My car stalled out, all the panel icons flashed when I was either braking and barely moving in traffic and when I would also turn on the heater. I thought it might be the fuel filter...and had it changed, but it was a minor expense.. The problem continues, though...will take it in to have the idel air bypass valve investigated. When I took it to the mechanic before he could not replicate the problem and only changed the fuel filter,because I insisted. I think I will take it to the dealership this time.

Everything in your description was accurate to the tee

As you accelerate half pedal rpms good and as you give it go to the floor bogs out

My car accelerated on it's on when driving. This happened suddenly without no other cause. When I start it up without foot on pedal it accelerates full speed while gear is in park.
