I have a 14 Silverado with the l83 5.3 and did a full dod delete a while back (cam, lifters, pushrods, rockers,etc) and now I just rebuilt it and bored out the cylinders and installed a katech direct replacement high pressure high volume oil pump. It was great for a day idling at 45 up to 80 under load. But then I got a p06dd code and oil pressure now will still idle at 45 when cold and jump up to 80 under load but when at operating temp it will idle around 10 or lower and under load jumps up to 80 still. Has anyone had this issue. Where should I go with the situation?
