She passed as she does every year, I need the car and could be asked to go anywhere in the country so she is serviced and looked after by the same indi.

But a question I forgot to ask for the last 2 years.

The report says "fast idle test = CO @ 2500 - 3500 RPM 0.00% And then natural idle test = 450 - 1500 RPM 0.00%

Is this normal for a petrol car?

I just wish to know what it means

The default limit for both is 0.3%, so 0% is about as good as it's going to get.
