600-800PSI at idle, 3000PSI under full load if you got a good pump.

yep, those are to low, are you reading them with a mechanical gauge?

It may be the IPR sticking, which they are known to do. its under the HPOP on the drivers side of the motor you can take it out and clean it, see if that brings the numbers up, otherwise its possible you have some blown injector O-rings and they are causing that cylinder to not fire causing the miss and low oil pressure, time to pull the valve covers and see which cyclinders arent working.

A trick to do first is let the engine cool, then fire it up and feel every exhaust port, the ones that stay cool are not firing, that will help speed up the process of figuring out which cylinders are missing.

once the valve covers are off fire the engine and look for oil squirting out the small square defelctor on the side of the injector, no oil, no worky. pull that injector out and look for cut O-rings.

If this is your 99, 460 - 550 is normal at idle. 1,200 - 1,600 at WOT is a problem regardless of what year motor you have. Is there any signs of oil in your fuel filter bowl?

If its a OBS Cali model the ICP at idle will be low cause they has split shot injectors
