I am needing assistance with the next step to take with my truck, 98 k1500 350 with 159k miles. It cranks hard, and has a random misfire while idling. Stutters while driving just enough to be noticeable and has extremely low oil pressure when warm, I have replaced plugs, wires, distributor cap and rotor button, IAT and OPSU. Oil pressure still reads 5 lb and below at idle and never over 25 lb even at 2500rpm. No noticable rattling or pecking as if it doesn’t have oil pressure. Is the misfire issue and the low oil pressure connected? Any help would be appreciated, thanks.
