I have a 2005 1.6 petrol focus, so heres the problem, the engine managment light came on about a year ago got it checked to see what the problem was and found out it was the cat which is being priced at £800 new.

I got the light put off by computer because it was up for NCT(same thing as MOT only irish) but then found out that it cant be the Cat or else it wouldnt go through the NCT(National Car Test) so i bought a new sensor for it, got the light put off but now the light is back on and someone might be coming to view the car next week as im selling it, i cant afford to put out £800 and cant find a second hand Cat.

Anyone know anywhere that does any Catalytics.
Thanks
