Yeah, I fixed the problem ... I just pulled all the plugs out,
cleaned the head where the plug sits of oil, dirt etc, cleaned the
silicon boots for the plugs, and the stems of the coils then reduced
to gap on the plugs to just over 0.8mm and problem gone.
The plugs Im running are pretty new. The are NGK R Laser Platinum BCPR6EP-11 3350 units about $20.00 AUD each.
Now it runs hard and smooth all the way to red line with 15psi .
Plugs showed no sign of overly lean mixtures and fuel cut mod appears
to be working fine. Its all good.
By the way the car is a 90 model JZA70 Supra and the engine the 1JZ-GTE with the stock twins.
