You are very close to passing, you could try richening up the mixture.

EDIT:
I just saw the CO number, you are running lean. A CO of about 0.1 is lambda (AFR of 14.7) and your down at 0.01
I'd get a reputable shop to setup your mixture properly and I bet you'll pass. Or if you have access to a wideband O2 gauge you can set the mixture yourself.
And as Joe pointed out you could have a small vacuum leak somewhere.
