2000 Mercury Grand Marquis Owner Comments

problem #1

Dec 022010

Grand Marquis LS 4.6L V8

  • Automatic transmission
  • 105,012 miles

A D V E R T I S E M E N T S

The problem occurred 3 times (2010, 2014, 2014), each time a different cylinder. One of these times, it occurred to my wife 140 km away from home. I had to guess that it was a blown spark plug and instructed her to drive the car to Toronto in this condition.

Concern: Aside from the costly repair, I am afraid to use the car on a long trip for fear that this will happen at a place where a repair is not available.

I suspect that the Ford company has modified the engine along the way, considering the fact that on a previous model I had owned for a long time (1993 Grand Marquis), the problem had never occurred.
