how to chang spark plugs in a 1992 Pontiac grand prix
yes
Remove the spark plug wires from your 2002 Mercury Grand Marquis spark plugs. Remove the spark plugs by turning them to the left with a deep well 5/8 socket. Reverse the process to install the new spark plugs.
one per cylinder
look on the very top of the motor and you will see a long rail them are the spark injectors for your spark plugs. pull them injectors out and you will see your spark plugs.
I would replace the spark plugs after 50K, the wires and plugs again at 100K.
Dirty spark plugs can occur on any make, model, or year. Changing the spark plugs should be done for maintenance, such as when you do a tune up.
