Could this be what I think it is? - carbon taste in mouth

My car needs an adjustment. I can drive the exhaust into the car smell through the openings, so with the windows open at the moment. Recently, I had a headache, was very tired, and I had this metallic taste in the back of my mouth that will not disappear. Is that a carbon monoxide poisoning?
