Well im trying again to sort it out. Its still throwing oxy sensor code even after ive fitted a new one. So i bought another 2nd hand one from a wrecker and just fitted it. And it runs perfect. So it looks like i bought a faulty new sensor. And thst seems to have been the problem all along. No more misfire and ticking, runs smooth and a lot more power.

Bloody frustratibg things these discos.

Think im still selling it though
