i have noticed after sitting at the lights for a while my idle starts to stutter a bit and little puffs of black fuel smoke comes out .today i retarded the cam as fare back as i could with the vernier gear .now when it just sits there idling you can see little puffs coming out all the time.when i give it a flogging after sitting there idling for a bit ,it belches out a big black cloud then its fine no smoke until i sit there idling again and it dose it all over .
i just recently replaced the o2 sensor,so it can't be that .is this just normal for running a decent cam ,it has a fairly lumpy idle .or could it be some other related prob ,like a stuffed map sensor or some thing.buy the way i am also running a unichip. thanks ,jake |
