it cud b a fukd cat 2! hard ta kno rele but id say lamda sensor is ur best bet ;)
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
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...!
I don't get the highlighted part ?? :confused:Quote:
