2007 6.7, my warning light comes on alot. I run alot of desert in my business and at night I have to idle to run my air or heater and the catalist warning comes on about every night, I have to get on the feeway and run alittle for it to clear, then it's fine until I'm setting the next night idleing and it comes on again and the same thing again. Is there a way to stop it from filling up so fast or do I have to stop idleing? thanks for any help, Hank

slow down on your idle time and use your high idle feature thats in your cruise control or have your whole exhaust system removed and replaced with a dpf delete system, but that will void your warranty if you had to go back to the dealer for some bs work....but if you know the guys at the dealer then you are golden!!!!

How do I use the high idle on the cruise> Did't know the truck had that on it. Hank

if your truck is a auto put it in park turn the cruise on and press the set button....it will bump up the rpms.....
