It is a JZA70 Supra with a JZZ30 1JZGTE motor & standard computer.
My misfire goes - da da da da and the revs bounce from 3500 -> 3000 (feels aweful).
Any ideas' ?
It only misfires once the car is warm (after approx. 8 mins) and only does it when I sit at or above around 110km/hr.
I can accellerate / rev past that sometimes though.....
