Scan for codes and check fuel pressure see if there is a misfire that may be why it's doing it. Then check compression and basic engine checks

Thanks a lot Mr. Hmac300.
Please note that, this problem start with me after repairing the engine, it exposure to high heat, and I make overall repair. And I changed the cover of radiator, because it was explode.
The cause of high heat was unknown, and still.
After repairing, I make valve labeled (photo attached) balancing.
After that I make complete test in Honda agency and they gave me report to change the engine mounting and throttle body.
I changed these as required, but nothing changed.
I make computer test after that, also no faults or misfire.
The rpm is stable, even after switching on the AC in the "morning".
But in the afternoon, rpm is going down suddenly after switching on the AC.
I don't know if the throttle body needs to be programmed or the problem is related to the radiator water temperature.
Please advise before going to check compression and basic engine checks.
Regards
