SportWEdge Posted January 18, 2018 Report Share Posted January 18, 2018 Hi All. Thought my tranny was having issues and took to AAmco. Tranny is fine but they said #6 cylinder is misfiring. Said it was probably the coil. I am by no means a mechanic, but does that sound about right? And if so, is it an easy fix? And now today....the engine light came on. Any help will be appreciated Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted January 18, 2018 Report Share Posted January 18, 2018 Could very well be right. Engine issues often pose as transmission issues, as the command & control of both is intricately linked. How many miles on your Edge, btw? You don't have to be a mechanic to read codes What you DO need to have, is an OBD II adapter to plug into the OBD port under the driverside dash, plus software like Forscan Lite on your smartphone/tablet. With those up and running, you can pull codes yourself and see what is going on with your Edge. Forscan Lite usually has a little blurb along with the code to explain basically what the code means. Or you can search for the code on the Internet, lotsa resources available, If it IS a misfire, hopefully it is just time for plugs, I would change them all. To be sure, verify the resistance of the coil drivers at the PCM, and the resistance values of the coil itself. Then you will know if the issue has made its way past the plug into the coil and possibly into the PCM. 1 Quote Link to comment Share on other sites More sharing options...
SportWEdge Posted January 18, 2018 Author Report Share Posted January 18, 2018 It has 115k. I don't have any tools so will have to trust a mechanic Quote Link to comment Share on other sites More sharing options...
Mikula Posted January 18, 2018 Report Share Posted January 18, 2018 Since you are not a mechanic yourself it is tough to give you advice on how to troubleshoot. I always give the same advice to everyone encountering misfires. check plugs first. pull plug #6 and see how it looks. plugs are generally so cheap/easy to replace, if you are not familiar with what a plug should look like you can just pop a new one in there and see if the problem is solved. a misfire can generally feel like what seems to be a transmission problem. jerking, surging, hesitation. i had a bad ring seat on a freshly rebuilt toyota motor and thought it was a transmission problem. turns out cyl #5 plug was trashed with oil causing a misfire. If it IS a misfire, hopefully it is just time for plugs, I would change them all. To be sure, verify the resistance of the coil drivers at the PCM, and the resistance values of the coil itself. Then you will know if the issue has made its way past the plug into the coil and possibly into the PCM. as stated here, this is the best way to check, but if you're not a mechanic that was probably all in a different language! if you are over 100k and never changed plugs it is time to do so with all of them anyway 1 Quote Link to comment Share on other sites More sharing options...
jamjordan Posted January 26, 2019 Report Share Posted January 26, 2019 I just had this issue. I replaced the plugs and coils and that fixed it. Quote Link to comment Share on other sites More sharing options...
fishx65 Posted January 27, 2019 Report Share Posted January 27, 2019 If you're gonna have your mechanic change the plugs and COPs I'd purchase the whole Motorcraft kit for around $150.00 and hand it to him. Comes with 6 plugs, 6 COPs and the UI gaskets. At the very least have him replace the back 3 while he has the Upper Intake off. 1 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted January 28, 2019 Report Share Posted January 28, 2019 You will have to buy plugs & gaskets separately for 2011+ applications. Still a HUGE savings over individual coil pricing. Plugs & gaskets fit 2007-10 since this kit originated out of the TSBs for the plug/coil/PCM fiasco. Quote Link to comment Share on other sites More sharing options...

Thanks for clarifying.!! I wonder how much longer these COP kits will be floating around. Pretty sure Ford would rather sell them individually!!!:) Quote Link to comment Share on other sites More sharing options...
