With 118 K miles on my truck I finally got around to changing the factory installed spark plugs today. The gaps were .078" to .080". It sure idles very smooth now and the gas mileage should get a little better too. :usa:

I did my plugs and wires once steady at 50K miles due to a random misfire. I'm about to hit 100k in the next couple months and will be doing them again.

Did you put dielectric grease on them? and what's the torque spec anyway? I see a lot of different answers when it comes to that.

Dielectric grease is not required if you use wires with silicone boots, but a small amount sure wouldn't hurt. Torque is about 25 ft/lb.

My cousins did all of the work for me. I am on SSDI and can't afford to lose it by doing this kind of work. Besides, my leg could not take the standing on for a long period of time.
Yes, dielectric grease was used, as well as anti seize also. And, they tightened them up until the rear of the truck started moving sideways. :roflol:
