Hmm ok. 1978 Toyota Celica miles unknown. just got the car.Around 278000 I would think. Was this a generic reply that you sent? "For us to be able to assist you, it is absolutely necessary for you to include the make, model, year and mileage of your car." Hmm I thought that was in the original post? Not tying to be rude. Just that I allready said that?

Yes, that is a generic response because you failed to provide the mileage. Mileage is the key to engine condition and emissions are dependent on engine condition.
I answer hundreds of posts a week and I will not provide a professional response to any question without as many facts as I can get. I owned and operated a garage for over 40 years+ and I do this work to help people.
At 35-40K miles the Japanese remove engines and replace them. Most of these engines are sent to the states.
You are very close to being in tolerance. Make sure you have good plugs (NGK) and your oil and filter has been changed. Change the air and fuel filter.
Clean out the throttle body with carb cleaner and an old tooth brush. You will find black deposits where the air passes over the throttle flap. Clean it with the throttle wide open so you can get to the black crud. Do this cleaning before you replace any parts as the engine will run a little rough when you first start.
Retard the timing 2 degrees and adjust your valves.(very important because a tight valve will not pass the exhaust gases like they should.)
Put in Amoco preminum white fuel and give it another try.
if that fails then the option is to replace the catalytic converter and O2 sensors.
You can do any of these you select and try the CO test again. It's up to you.
