I was a school bus mechanic awhile I had over 260+ buses most all were dt's, t444e, or 7.3l units... I have seen this caused before with a bad injector pressure regulator... it's hard to tell you how to test it without a scan tool. on a scan tool it will show injector pressure on data stream... if you replace the hpop get a super duty unit it is a 17* vs. a stock 15*... it will help the truck wake up a lil bit I have seen them on here for around $350
