Danielle Posted January 4, 2023 Share Posted January 4, 2023 Does anybody have the specifications for primary and secondary resistance on the coils for a 2012 3.5L? I put my triton D10 on it and the spark duration on cylinder 2 is all over the place compared to the other cylinders. I don't want to just throw parts at it. But I can't find the specs anywhere for coil resistance specs. Any help would be appreciated! Thank you! 0 Quote Link to comment Share on other sites More sharing options...
WKelley Posted January 5, 2023 Share Posted January 5, 2023 Swap 1 and 2 and 3 and 4 and see if the misfire follows. I don't have the spec your looking for though. 0 Quote Link to comment Share on other sites More sharing options...
Bop Posted March 22, 2023 Share Posted March 22, 2023 Check a resistance on a coil you know isn't miss firing or even easier swap coils to different cylinder. Be careful! Make sure its ignition miss and not a rocker shaft bolt loosening up and causing reduced lift on valves leaning it and causing miss. The early 3.0 had this problem. I think latter years it was corrected. My 2 sents. Bop 0 Quote Link to comment Share on other sites More sharing options...
