Looks interesting? Are you nervous about disclosing your source for delivery to Ireland cactikid? No point in giving us half the story now, is there?

post back what you think cact as iv a mot in october might be worth investing in.

found a supplier on ebay
CATACLEAN CATALYTIC CONVERTER CLEANER PETROL & DIESEL | eBay

i used it many years before and it vanished,it may be expensive but what about getting another car to replace the one you drive

i have tried about 4 or 5 similar treatments, the machine showed that they did not work, oh cactikid i now drive a toyota estima, some comfort for little money.

forgot about this thread ,it must be a different mix as the one i remember if you had a smell of it you would be high as it smelt like acetone,new stuff no smell and had no difference on emissions sorry to say.

Have you tried getting a throttle body cleaning and a fuel injector flush?
Have them check all the O2 sensors, if these are not working correctly you will def. fail the commissions test.
