sparkplugs.JPG 93.37KB 1 downloads Not in bad condition, gap was still .05", but when ICE was hot and accelerating up hill it would run rough sometimes after I used injector cleaner. Seems to be working fine with no noticeable problems. I went from SP531 to SP530 plugs.
Update the problem was right half shaft CV joint, no change in MPG's so I didn't need to replace Spark Plugs after all.
