  • 300 hpdi rough idle stalls

    Hello everyone, I have a pair of 2005 300 hpdi's Z300txrd/LZ. I have done fresh gas w/ringfree and seafoam,double racors,new primers,rebuilt lowpressure pumps,new water separator filters,new vstpumps/strainers,new med pressure filter,cleaned 4 mystery filters at high pressure pump,new plugs,new Tstats. Both motors start and run strong all the way to 5400rpm.The strbd motor idles rough(rougher than port motor)and stalls after a few minutes but will start right back.I will have YDS software in a couple days and hoping for some ideas to get this thing running like it should. Thanks in advance for your patience and valued advice. Ken
