has any1 got any suggestions on how i can drop my emissions??? i have a full standerd system on it incl cat! its only failing on high idle CO 0.51 %. a fail is above 0.30% so im 0.21% out i didnt try dipetane yet but will it reduce it this much??

Dipteane is know for it as says on the bottle and cleans aswell. Try that and a bit of wire wool.

everything is spot on apart from high idle co 0.51%! my lambda 1.01 its ok! there is two cats in my exhaust i cut the silencer out of the standerd 1 i had and welded a cat into it that has only 3000km on it! its not my cat! im after putting the whole standerd set up from my mani to the full cat back exhaust wit silencer took out nd another cat inplace and a direct fit jasma stamped back box! what causes the CO to be that high anyway does any1 no??
