2008 Nytro has dead misfire on center cylinder. I have used the onboard diagnostic tool coil fires as it should, I can hear the fuel injector fire like it should. It is always the center cylinder, swapped the coil still middle cylinder. I have not taken the injector out to check it. I am thinking about running some sea foam and some new gas. Just have not had enough snow to ride this thing the past 2 years so I am thinking blocked injector. Anyone else had an issue like this? Any help would be greatly appreciated. I should mention it started after storage.
