My CO IS 3.56 percent and an MOT fail. Pass would be 3.50 percent. My minimum idle seems to be 1000rpm. PCV is clean. What would be the most likely cause of my High CO?

I don't know the tech exactly. But when was it last serviced?

Has had oil and filter replaced and plugs cleaned and timing checked in last 100 miles.

I believe a vacuum leak is often responsible for high idle and CO.
Rhinoman who has recently joined the forum
will be the most knowledgeable person and hopefully will be along to help.
I assume the check light is not on.
Dam ECU's are beyond me

Rhinoman has an identical Vit to me so I would love to hear his thoughts. I suspect a vacuum leak also.

Did you buy a tool from me a while back? what do your fuel trims and O2 sensor readings look like?
