Ignition issue on turbo ls6
Ignition issue on turbo ls6 Basically I will give a run down of a random issue I've been having. Basically car will idle and run strong. Then sound will change and a whole bank of coils will just quit working. Sometimes it will come back and cut out. Sometimes it runs fine. Very random. As far as things I've checked and looked at. Coil packs are relocated and all seem to work. 12 volts is supplyed via the pink wire even when a side drops out. grounds on head are attached via one bolt. " I was told that they need to be seperated on two bolts?" Have yet to try that. Plugs are tr6's with new wires and all protected from heat. Engine has two heavy grounds. I visually check the spark at each coil and when its running good a nice purple spark is there. When a side drops nothing. Even more bizzare is if I pull a wire off the coil it will bring the side back almost like there is a interfence in signal or something. Hope thats enough detail but feel free to ask if I missed something.
