Question about 2001 Mercury Grand Marquis
Have the vehicle scope tested. This way they can pinpoint the problem. Otherwise unless there is a code that is causing this, the tech's have a guessing game on their hand.

Withoutknowing if the check engine light is on it could be a variety of things including but not limited to the o2 sensor, throttle positioning sensor, and the MAF and MAP sensors. Best diagnosed by using an OBDII scanner to scan for codes. If no codes are present I would then check for the pressure coming from the fuel pump to make sure it is still functioning.

If it's not injected, the idle circuit in the carb either isn't adjusted properly or is plugged, or the float level is too low. A vacuum leak can also do that.

This sounds like a problem with the idle control. The idle control has to be adjusted. If it's not an idle control, then it would help to know the year, make and model of the car and the mileage on the car. At the simplest, it's the idle control. However, it may also be a problems with the car's ECU.
