its to the point where the C02 alarm goes off in my garage, lol, Is this normal?


what could be causing this

The injector fuel lines may be leaking. Open the hood and have someone watch as the engine starts. If so, shut down immediately.

You need to check fuel pressures. Likely your Warm Up Regulator is kaput.

No.

what could be causing this (?)

If this is unburned fuel in the exhaust, the mixture is either way too rich, or the engine is misfiring. However warming up an engine by idling is hard on it, especially due to oil contamination. Best to start it and drive, and yes I know that's easy for me to say from a warmer climate.

Correct.

I have a car named “red Smokey” bc the fuel distributor sent full throttle fuel to cylinder #4 from the moment the car started. Not only did it smoke like crazy from the unburnt fuel, but of course it would smell. No amount of spark would fix that combustion issue, but typically the very first thing I do when a car is smoking is check to make sure all the spark plugs are firing. Timing loop is the easiest for me.

And that “red Smokey” was apparently giving a previous owner terrible fuel economy for a long time. They apparently didn’t trace down the issue, and the exhaust manifold wold get red hot. It eventually cracked. We replaced the exhaust manifold and fuel distributor and the car is now a good driver. I think the compression is low all around though due to wear caused by rubbing the car with gasoline filled oil washing down the cylinder walls. Iron block lower ends are robust, but this one will never be a racer.

So track down the issue.
