Ignitor ground?

[93_jdm_fd]

I have miss at idle. I am using an rb20 coil harness in my gtr and I don't have my center coil cover installed because of the rb20 harnes routing. At the moment I've been running with the ignitor just laying there and the ground not hooked up.

I know this is probably stupid but if this ground is not hooked up could this be causing my misfire at idle? I can go through the entire rpm range, full boost and not a miss at all. I slow down to and idle at a red light and the car misses slightly.

Try grounding it and see if it helps.
You can mount it to the valve cover with one screw in an existing thread used to mount the cover.

Good luck

I will try to just bolt it to the valve cover tomorrow. I just don't want to cut into an already brittle harness to route it properly. I'll just get the gtr harness, which i was told this one was. I didn't care because this one is better than nothing.
