Hi Idle setting
Hello all, my 99 7.3l powerstroke is finally running like new. 200, 000 on the clock but after 8k into the engine she runs so well. Heres my questuion to those who may know more. About midday each day in central cali where I live temps rise to nearly 100 or higher. For about an hour each day I find myself resting or napping in the truck before going back to hustle of work. I keep A/C on max, and just idle her. The temp guage never moves above what it always is, idle is smooth, although the A/C is just very slightly less efficient than if I was driving. I also have a chip on her with a dial on the dash that has a setting called HI among 6 other settings. If I switch her to high idle the RPM jumps to 2100. Fearing that this is too high for idle I leave it off and go to normal idle. Is what im doing safe with normal idle in 100 degrees for one hr everyday? Or should I just switch her to 2100 rpm from now on? Staying inside my work place for my break isnt an option. Ive heard mixed things. Any other outside the box solutions? Like changing to certain motor oil in summers??
