2nd nct emissions fail

bibi691 · 2015-04-09 22:29:05

Hi am new here so not sure how this works exactly but sure here goes. I have a 07 vectra c 1.6 petrol, which has failed nct again on emissions. First test readings came back on high idle lambda 0.97, co 1.15, someone suggested throwing dipethanthate into it so i put about 500mls into nearly half a a tank and drove it hard…

Hi am new here so not sure how this works exactly but sure here goes. I have a 07 vectra c 1.6 petrol, which has failed nct again on emissions. First test readings came back on high idle lambda 0.97, co 1.15, someone suggested throwing dipethanthate into it so i put about 500mls into nearly half a a tank and drove it hard for about half an hour tho as i learned today
that wasnt hard enough anyway took it down today this time lambda was0.98 and co 0.93, do i need to replace cat converter or should i try dipethane again only properly next time
