Code was for random misfire and misfire on cylinder one. After inspecting cylinder ones plug and seeing that all looked well I headed over to the parts house for new plugs and wires. I started with cylinder ones plug and wire and discovered my problem. The wire had a huge crack in it exposing some of the bare wire. Changed out that plug and wire and fired her up. Ran like a top. Since im already in it for the whole set of plugs and wires I figure its time to replace them all. Only have one plug and wire left and im finished. Now that im not working today and in maintenance mode, I figure I will change the oil and filter while im at it. Shes only about 500 miles off from her next change anyhow. I dont have the owners manual for this truck yet and I just need the specs on oil viscosity and capacity. Also curious on when its recommended to change the pcv valve and breather?
