I am wondering if anyone knows if there is any damage being caused to my car running on only trailing coils?? Accidentally fried out the primary coil.

Well I'm getting a new coil pack soon but i was wondering if running on trailing would cause any internal damage.

High egts, you could damage the car.

Ignore the above...

You won't do any engine damage, but you'll be severely down on power due to only partial combustion taking place. Running like this for will quickly damage the cat convertor if you have one.

Yeah no power is actually what got my noticing something was up. I knew something was wrong when I pulled out of my driveway and i killed it... T-T

Lesson learned: Double check what you ground ha ha.

What exactly did you ground? I'm not sure how you could've damaged the coil.

There's absolutely no need to add any extra grounds to the coils; they are grounded directly to the chassis through the ignitor body. The most you need to do is clean those mounting points.

I meant to ground the test connector when i was checking my timing and I saw the black wire coming off the primary coil and i was just sort of like yeah thats it and grounded it to the body and as soon as I did I was like crap the test connector is green. Woe and behold no spark from the primary coil. It s the black connector that is used to check idle speed apparently. supposed to put a tach on to it or what not.

you could make it better as a short term quick fix by connecting the trialing coild plug wires in the leading position and advancing the CAS. Be really carefull if this is a turbo, keep it out of boost.

nah no need to risk damage. Car is sitting this week. Going to do some wiring of a switch for my EGI fuse. Cheap security and if i ever need to flood clear ha ha.

NZConvertible

Yeah, that might do it...

So anyone reading this if you don't know what the hell it is research it. After messing up my coil I looked up the black wire and found out what it was for! Search is not only a good way to clean up the forums its a good way to protect your car!
