We just had an add on framed in, and I am worried about the CO2 seaping up into the bedroom through the floor and where it hooked onto the house. IT was just attached to the side of the house. I have thought about sheet plastic, but how do I seal where it is against the wall? Do I use that spray foam? We could not afford the builder to compete the job.

You cannot ever seal off a house. That is because most gas furnaces and heat rising causes a negitive pressue within the house proper. And air needs to enter to balance it off. Ant it will find every crack and crevis no matter how minute to do so.
You protect yourself by adding a 'makeup air" pipe to your furnace intake along with a balance flap valve that allows make up air to provide a positive + pressure within the house proper . That is the best solution I know of to date .

Well actually you dont need to seal it...CO2 is heavier than air...so its all going to stay in the garage...unless there is some active draft which will convect the CO2 upwards...so CO2 isnt the issue...if you run the car in the garage carbon monoxide might accumulate along with the CO2 and CO is about the same weight as air so it could creep upward but most likely it will stay in the garage aslo. You may get fumes from unburnt fuel (hydrocarbons) that may be a bit unpleasant - ...one solution that may be your easiest and best solution is to ensure that when ruinning the car in the garage you have sufficent ventilation...install an extractor fan similar to the bathroom fans but ensure that it is large enough to exchange the air several times per X period of time (I cant recall what the exchange rate ) ...you should consult the uniform fire code (library may have this) for your state which will tell you how many air changes per period of time is required. Mount the extractor fan or fans at mid and high level on the wall nearest where the car exhaust is likley to be...be careful not to locate the extractor fan discharge within 3 feet of an operable window....
Extractor fans come in ratings of cfm or cubic feet per min, all you need is the cubic feet of garage space... divide the garage cubic feet by the fan rating in cfm and that will tell you how long it takes the fan to exchange the air in the garage...
Good luck

CO2 is not dangerous. It's the Carbon Monoxide that is lethal. I think you should buy a Carbon Monoxide Detector to plug into an outlet in the room over the garage. Some of these detectors/alarms are battery powered and are available at Home Depot or Canadian Tire Stores. They work to detect the Carbon Monoxide gas that can seep into the room when a car is left running with the garage door closed and you or a family member is sleeping in that room. They squeal loudly when this gas is detected.

5/8 sheet rock with all the joints taped and plastered is all you need. Also be certain that the door to the garage from the house, is a steel door with full magnetic seals all around and a good threshold seal at the bottom as well.

Do you mean CO?
Are you leaving your car running or building a campfire in your garage? If you are, then there is no way to seal off the rest of your house.

Open the garage door when an engine is running.

Sheetrock is the way to go.But you only need 5/8s if you intend for it to be a fire break 3/8s will seal it just as well and be cheaper.
