What's your problem?I have a 2000 Lincoln LS that runs great when driving but as soon as I stop and sit a minute it cuts off. I have noticed the car start stalling a little before it cuts off. Cou


Generally speaking, the common reasons for stalling are a faulty idle air control valve or a dirty throttle body.
The computer controls idle speed by how much air is allowed into the intake thru the throttle body.
Those two issues would be checked first.
Is the check engine light on when the engine is running ?

When my lincoln town car 1993 dies when i stop do i have a serious problem?


No read the fix below.

Engine stalling issue at low speeds

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Lincoln LSI 6 c, motor will not idle, always dies when I stop.


Symptoms indicate a dirty throttle and idle air controller interior. Remove the air ducting between the air cleaner and the throttle. Use a cloth and WD40 spray and clean the throttle interior and throttle plate. Rotate the plate and continue cleaning further in. When all clean reinstate the ducting and test.

05 Lincoln LS 3.0 V6. Outside air temp 32F. Idle decay when cold


This sounds like you have a pcv hose that has become an open vacuum leak. It is located under the upper intake, or given the year your air filter box may not be correctly sealed and possibly have a mass air flow sensor concern. Any Check engine light or codes to work with ? I f you have further questions just leave a comment on my page,

What is the function of the idle speed control valve?


The idle air control (IAC) valve assembly on a combustible engine monitors and manipulates the amount of controlled air moving around the throttle plate. The IAC valve is managed by the electronic control module (ECM) of the engine, which calculates the position of the IAC valve. Voltage pulses called counts extend and retract an internal conical-tipped shaft called a pintle inside the IAC valve. When the pintle is extended, the cone-shaped tip positions itself closer to the air inlet and restricts the amount of air allowed to pass through the throttle, building up more air around the throttle plate to increase the rpms of the engine. When the pintle is retracted, it moves away from the inlet and allows more air into the throttle away from the throttle plate, decreasing the rpms. The IAC valve operates and adjusts constantly while the engine is running to help prevent the engine from stalling or surging. This will not cause the engine to misfire!! Hopefully this helps
