Mazda North American Operations has recalled more than 5,700 vehicles with five-speed manual transmissions and V6 engines to help control the vehicles' emissions. The recall covers 2,274 of the model 626 sedans and 3,504 of the MX-6 sports coupes from the 1995 model year. The cars may produce exhaust that does not meet federal standards. Cars originally sold in California and Massachusetts already meet California emission specifications and are not included in the recall.
Owners affected by the recall can take their cars to an authorized dealer to have a vent kit added.
The kit will allow a small amount of air into the intake system to lower carbon monoxide levels in the exhaust.
