change lamda sensor maybe?

[rdrifter]

ye that was first on my list mate, pricey pain in the arse all the same (we when add with wath else i need)

the SUBZERO weather wouldnt effect the emissions in anyway would it?

[Diesel-Dick]

it cud b a fukd cat 2! hard ta kno rele but id say lamda sensor is ur best bet

[rdrifter]

cheers mate ill do the lambda first see how it goes.. cheers

Put up the reading's to give us an idea?? could be load's of different thing's causing it, no point really in just guessing and firing parts at it

[rdrifter]

low idle : CO 0.06 vol% / above 50% fail

(770rpm) HC 6 ppm / above o ppm

high idle : lambda 1.00 / not between 0.97 & 1.03

(2,920 rpm) CO 0.47% / above 30%

HC 39 ppm / 200 ppm


here it is as i read it...!
