Evening all,

Having problems with my 4X4 Sapphire, I've had my T34 rebuilt as the bearing let go in it since I've put it on its developed a misfire as soon as it comes on boost, it drives absolute mint pootlying around but as soon as I put my foot down and the boost gauge hits one bar and it's starts misfiring.

Even if I feed the power in it still does it.

I tried a fresh set of plugs in it (071's) just to see if it would help but no joy.

Any ideas people? What have I done!!?

Starting to pull my hair out with it and all I want is get out and use it.

Cheers, Oli.
