Well those are misfire codes which explains your power loss,and if your losing power/misfiring when the engine overheats....all signs point to head gasket failure
The burning of coolant is causing the misfire/power loss

i checked the codes everything has been ruled out and i think it might be
the catalytic converter getting a straight pipe installed tomorrow see if that works

maybe knock sensor is bad. IDK look up bad knock sensor on Google, Worth a look IMO. Converter is a possibility. Would temp have an effect on power though if it is the converter. maybe through expansion closing the honeycomb.

You have a misfire in cyls 1 and 2. That has absolutely nothing to do with your cat. When was your last full tune-up?

Let the engine idle to warm up, then turn it off and test the plugs. Also, check your injectors.
You have a misfire. A cat isn't going to fix that.

Do a compression check, might be a bad valve. Too bad you didn't freshen the head when it was off would of been easier that way.

Could be head gasket maybe block was warped also. Was it decked as well? ^ makes a lot of sense.
