Ok, I haven't been driving my 97 Mark VIII (my mom has been driving this car)because I got my hands on a 93 Mark VIII. So today, I felt the need to drive my 97 Mark VIII to college. It started a little rough but it did start. So When I got to college, did some studying, I went to go eat. It started rough again. I ate, came back to my car but it wasn't starting. I hear it clicking (starter), my battery is fine because usually when the battery is bad, all the lights go out. It has 97,000 miles. I am guessing its the spark plugs What do you guys think?
