On my truck the difference is too low an idle which makes the brake booster run low sometimes or too high which makes the universals in the driveshaft sound like theyre in pain when I shift into D.

 

Thinking about this a little, it seems all we need is pressurized fuel at the injector nozzles for an instant start. Could this be a simple governor adjustment since this is what regulates fuel to the nozzles?? Make sense?

This is what I get for thinking sometimes

 

Here is another thread that points to the starter. Best keep the starter in mind. https://www.dieseltruckresource.com/...d.php?t=184920

 

Thanks ET RAM, looks like i'll be taking the starter off soon. Think I have a leak behind it anyway, so maybe i'll take care of that too.

 

i had this problem for like 3-4 months and finally my starter went out last week so had to replace it. but yeah just keep the starter in mind
