Today it is really hot. In the 90's and very humid. I love it! Yesterday it was 85+ degreesand slightly less humid.
Yesterday, my brother-in-law and I installed new pads and rotors, plugs and wires, and an oil change on his 1998 Explorer.
Plugs and wires were original. Some were so worn down, the gap was as much as 1/8 inch. Over double the recomended gap.
I guess after 143,337 miles, they needed to be changed.
