Finally Going Single! Part 2 by cohbra

Sure enough, I had bad plugs again. What the hell? I picked ups some BUR9EQ's from the local auto parts store to just throw in and see if that was my issue, and it fired right up. I don't think I'll ever try using the B10EGV's again, that's two bad sets from two different sources now. 

I talked with Jason @ the RX7 store and he said that the oil and smoking was probably due to the fact that I wasn't running a PCV valve. I'm not sure I understand how a PCV valve will affect oil leaking out of the turbo and into the exhaust, but I'm putting it all back together to give it a shot. The good news is that it is not coming out of the motor.

I got it all back together and fired it up but after I pulled it out of the garage it died on me and there was a bunch of white smoke billowing out from under the hood from an obvious electrical short. When I opened the hood I found this...

It's always something!

Yup, not sure why either. I just moved my coils to the frame rail and re-wrapped the harness to clean it up, but I didn't make any modifications to it. I added a ground strap from the coil mounting bracket to the ground point on the front iron by the spark plugs, but that shouldn't have done this. I read something about there being an issue with the ground on the coil harness causing arcing or feedback or something like that and frying the leading coil or wiring. Apparently, Mazda stopped putting a ground wire on the harness because of this. My lead coil signal wire appears to be where the short started too.
