I have problem access the 6th and 7th spark plugs in 96 Mercury Grand Marquis. The V8 engine has spark plugs positioned:
3 center 7
The 6th and 7th are under the Air filter hose. And there is a cover in the center, make it inaccessible from above. I tried to take out the cover, but failed to detach it from the hose.
(the cover is very simillar to the one in the center of picture:
While my Haynes manual shows Crown Victoria model is much easier to access the spark plug because there is no cover above. I am wondering if anybody has the experience replacing the spark plugs in Grand Marquis.
Any suggestions are appreciated. Thanks.
