P1678 & P1264

Ok guys couple weeks ago noticed my truck running pretty ruff at stop lights and such not so much in park. Ran diagnostics and these codes popped up (no engine lights on cluster) cleared them out and truck ran fine.. trucks still running fine like nothing happened but ran diagnostics just to check and was still throwing the P12678 code.. like I said truck isn’t running abnormal and haven’t thrown the P1264 code again.. I know the one code P1678 is for low oil pressure and P1264 is for the number 4 injector I believe? Just want some opinions on what actions I should take and what could possibly be causing this.. any input helps guys.. thanks

Check the wiring harness going to the injectors to see if they are damaged from chaffing or rodents.
