Good morning all, This morning on my way to work I was watching my fuel psi on my cts2 monitor. I do not have a programmer. At idle with my foot on the brake I read around 5.2-5.3k psi and at wot the most I’ve witnessed is 17k. This seems low to me and I want to know if it’s something I should be worried about. I have no idea if/when the injectors were changed. My truck is a 2003 non ho 5.9l 47re 3500 4x4. My truck does have the lope at idle every now and then when warming up. The fuel filter was changed 2000 miles ago. Truck has 319k on it, was bought with 310k on it back in December. Thanks in advance for any and all input.
