Hi!
I'm having still issues with my car after swapping my stock engine for a zc non-vtec sohc engine. The engine is a zc non-vtec engine and its all obd0. Now the car overheats when the weather is hot. Theres no leaks. The radiator is full of water. When I drive it the check engine light comes on for the air idle valve and it loses power (rpm acts funny). My friends gave me my car incomplete because i needed more $ to leave it 100% good. But now I don't know what I need to buy. And they are always busy now for me. I'm already feeling that I just want to dump my car down a hill.

Try bleeding out all the air in your cooling system. looks like you might have some air bubbles for it to effect your iacv and since your at it. Clean the iacv as well.
