97 6.5 surging issue? please help!!!
My 97 6.5 have a surging problem, the rpms will go up for a couple seconds and then back to normal for a couple minutes then back up for a couple seconds etc etc when idling, when driving ill be driving along like normal and then the truck will act like I floored it when I didn't do anything but it only lasts for a couple seconds then goes back to normal and it keeps doing this and I have no idea why, I'm not throwing any codes or anything, could it be a malfunctioning injector/injectors? Or am I completely wrong? Please I'm in dire need of help on this, I desperately need this truck 100% for work purposes

The PMD can cause hard starting but the IP fuel solenoid can cause that as well.
Another common reason for hard starting is a leak from the fuel heater or water in fuel sensor O-rings in the filter housing.
When they leak air is let in to take the place of lost fuel and hard starts occur after an extended sitting period.
