when rebuilding my mate said the bolts were slightly loose so he nipped them up but i havent checked myself, im baffled to be honest pull the no3 lead or inj/plug makes no difference??
No 3 has compression and after 2-3000rpm it clears but if you take the fouled plug out clean it put it back, run the car at idle , take plug out again its wet with fuel? drive the car over 2-3000,, do the same and its black again what could make the car run on 3 cylinders but clear when driven over certain revs? ive only experienced this in past at high revs with previous cosworths
