I will get a new set of regular plugs and see what happens when i install them without the anti sieze on the theads. Maybe these shortie plugs are to blame for the problem??

Personally i think it's an issue with fuel loading up in the carb due to the transmission getting into overdrive too quickly. I say this as if i shift manually and stay out of overdrive untill over 2500 RPM the problem does not happen.


I can stand on it and let the transmission shift automaticly and no popping issue all the way to redline....
