couple things to check.are the cooling fans
working? is the coolant full and free of air?
has any coolant work been done? when was the
last time the thermostat and radiator cap was
changed?

The cooling fan is working just fine, I do keep the coolant full, and the thermostat was replaced (with aftermarket part) this past fall. And I actually replaced the radiator cap a couple weeks ago. I know when the thermostat was replaced the coolant was flushed. But it still could be that there’s air. Another thing it does is as it’s overheating, the resevoir tank fills all the way up, sometimes spills out and the cap is as tight as crap.

Code 1 and 20. I haven’t checked either vacuum hoses or intake, but that’s def. a good idea. I was thinking cat convertor might be clogged. But issue also seems electrical to me. But I really have no idea where to start.
