Thanks

I don’t have a gun but may be able to get one however this eaving we installed a numbered water temp gauge in addition to factory gauge .Thanks for your input

04 Mack AI 350 HP empty or loaded turbo engaged goes in and out and heats to beginning of red on gauge stop and cools down quickly . Only codes is 3 injectors mis firing . Fan working ,Radiator ,air to air, ac condenser cleaned .Replaced map sensor / boost sensor, changed both thermostats , pressure checked air to air with no leaks . Could these 3 injectors that show misfire cause water temp heating problem . Thanks in advance for your Mack knowledge. Been a truck owner many years but new to the Mack game.
