deto can be a cause of plugs getting loose also.

X2 deto will shake them loose...no need to be way tight...leave them below torque spec(12lbss/ft) ? is spec i think...i leave mine at like 8 as if they come loose it's because of deto usually. look for small specs of metal on the electrodes and insulators and check piston tops for signs of deto.
what fuel do you use?
