Sorry to hear prob like that. First, I must disagree about RPM factor. Second, you should flush the cooling system and replace rad cap with a factory one and t-stat. Third, you should get either new injector or get your existing one rebuilt as it sounds like it needs to.

Many ppl just keeps on topping coolant rather than change every season. I would also recommend you to change all fluids and gear oil, including brake fluid.

When you're done with coolant make sure all the air bubbles are gone since air in the cooling system do cause ineffective cooling.

BTW, how hot did it get?
