This year had a central fuel injection with the idle speed on the side of the throttle body in the form of a D.C. motor with mechanical adjustments.
i have a 2002 grand marquis and when i driving on the highway at speed of 60 to 70 the light of traction control star to flash way is the problem
on the transmission
the cold idle is controlled by the PCM ( power train control module) the computer of the car and idle is not adjustable.
check fuses then refer to the speed control sensor which is on the throttle body closest to the air intake hose that controls the engine idle and speed control. Good luck.
It's one of two switches located on the Break Pedal. One controls the Brake Lights and the other controls the Speed Control. Hope this helps
Around 120 mph tops.
On a 1989 Mercury Grand Marquis, the cruise control speed sensor is typically located on the transmission or near the speedometer gear. It may be mounted on the transmission case or connected to the vehicle's speedometer cable. To access it, you might need to lift the vehicle and inspect the transmission area. Always refer to the vehicle's service manual for specific details and diagrams.

If the traction control light in your Mercury Grand Marquis keeps coming on, it could be due to several reasons. Common causes include a malfunctioning wheel speed sensor, issues with the traction control system itself, or problems with your vehicle's ABS (anti-lock braking system). Additionally, low tire pressure or worn tires can trigger the traction control system. It's advisable to have the vehicle diagnosed by a professional to identify the exact issue.
To adjust the curb idle on a 1984 Mercury Grand Marquis, locate the idle speed adjustment screw on the throttle body. Start the engine and allow it to reach normal operating temperature. Use a tachometer to measure the RPM, then turn the idle speed adjustment screw clockwise to increase or counterclockwise to decrease the idle speed, aiming for the recommended RPM specified in the owner's manual. Finally, recheck the idle speed after adjustments to ensure it’s within the correct range.
