to high emission, what's to do?
In idle the co2 sensor says 0,350 V, Co is at 10%+, at 2500rpm it's 4-5% the sensor says 0,280volt. could it be the Co2-sensor.
The problem started after I put new headgaskets in.
Thanks in advance

High CO2's signify a rich condition.. usually mechanics just have to change the air filters. Are yours new?
Oxy sensors are spec'd to be replaced around 35,000 miles... altho that's rarely done. If yours is as old as the car, then yes, that oxygen sensor might be contaminated.
