d00d- I guarantee that you've piddled away MORE THAN ENOUGH MONEY to have gotten it fixed long ago. If you want to get it fixed, quit making excuses/stalling and get it fixed.
Carbon Monoxide | Basic Information | Indoor Air Quality | Air | US EPA
The problem with carbon monoxide and people showing up in respiratory distress in the ER is that CO binds in your blood the same way oxygen does. You're probably having the effects of it right now and don't even know it.
What you've done by removing your exhaust from where you've removed it is single handedly the stupidest thing you could have done.
It's not funny.
