abs351 Posted October 13, 2022 Share Posted October 13, 2022 Greetings, I have a 06 Nov build Territory Turbo Ghia, with an issue prior. I diagnosed being the coils, of which the car under load will just breakdown in high RPM and trans will make a big bang , dash lights come up and speedo will stop working, once dash lights disappear after a split second (ABS, DSC, Traction control) car will operate again as normal, but no speedo..no DTC errors appear also. I have chased this issue down to being coils...once changed all working well. Other day I gave the car a boot full, back fired at high rpm between gear changed and started to miss. Thought I hurt the motor, but cylinder 6 coil failed. I replaced and off we go again with no issues.. gave it a boot full again and the phenomenon of trans banging and losing speedo appeared..So I suspect another coil is playing up.. if you drive car under normal load..all fine..moment you lean on it, reappears.. spark plugs are checked and gapped to .7 question...is there a way to load test the coils? Or what is the underlying issue if anyone seen such problem? I know how to address, just replace all coils,but I want to trouble shoot which one and what's causing this..I suspect a high current or Spike in voltage causing this... Original set was factory, second set was old non genuine laying around..I replaced cylinder six with a genuine. Regards Abz Quote Link to comment Share on other sites More sharing options...
