It may just be a problem of burning oil, but here's a long shot.

Measure the charging system regulating voltage. Take your car for a drive to 
warm up the engine and stabilize the charge on the battery, then pull it into 
your driveway and leave the engine running. Connect a voltmeter across the 
battery and bring the engine speed up until the voltage doesn't rise any more.

That voltage should be 14.1-14.4V. If it is less than 13.5V replace the voltage 
regulator with a Bosch 30-019.

Low system voltage makes the FI run rich, which would give you high CO. If this 
is your problem, replacing the VR will make a dramatic difference.
