Quick question, car is intake E headers and IM. Recently started detecting KR and a misfire count consistently showing anywhere from 2-10. No kr under wot, but shows a range of .5-6.7 sporadically for under part throttle (for example passing a car on the highway, getting up to speeds). Timing where it’s happening has been reduced, ran through two tanks of E from two different gas stations to rule out bad gas, and plugs look good. Does anyone have any ideas?
