[QUOTE="other365, post: 1570096, member: 39170"] From what I read the lower plug fires slightly after top plug to burn any left over fuel for emissions. The truck could theoretically run with no lower plugs, but would probably be unhappy. Put about 50 miles on it so far and no more misfires on 8 but it will take at least a few more weeks of driving to see if it fouls up again. The top plug of cyl8 looked new\dry. Thats what really gives me hope that the bottom wire was flakey. I will be ordering a compression tester and cheapy bore scope to have around for the next time I pull plugs. If anyone has any recommendations for > harbor freight quality but still budget let me know. [/QUOTE]
