Hello, I honestly do not know of any temperature related concern with this vehicle. I would probably suggest a valve adjustment for the engine, plus a compression test and check of engine timing. Nonetheless, I'd definitely seek guidance from a local technician who can experience your concern first hand, determine any variations or symptoms first hand, and use diagnostic equipment and workshop manuals to help figure out what is going on.
