I have a 2002 Jeep Grand Cherokee with @ 70k miles on it. The engine is a 4.0 V-6. Someone gave me a set of spark plugs so I thought I would change them just to see if the gas mileage would be affected. BUT I CAN'T FIND THEM! I feel rediculous, but where the heck can I find them? Do they have to be changed from underneath? Sounds simple enough to change plugs, but they sure aren't very visible.
have the same problem?
