Asked by Mar 15, 2014 at 06:11 PM about the 2003 Mercury Grand Marquis GS

Question type: Maintenance & Repair

I have replaced all coils, plugs, and fuel filter. The car has never thrown a code for this
problem. Still have the problem. Any suggestions?

Try turning off the Overdrive when the sensation begins. You may have a transmission component that is malfunctioning - like Overdrive gear itself or the Lock-up torque converter. A power balance test would definitely show you if the engine was indeed missing.
