Low oil pressure/ v4 mode vibration

[Jgarner]

I've got a 2014 Silverado 5.3 and I've noticed recently the oil pressure while at idle was around 20 pounds. During normal driving it's up to a little over 40. Also while traveling down the highway around 65mph the truck dropped on to v4 mode like normal however when it did it felt as if the truck had a serious miss. It eventually got bad enough it threw a code for the map sensor. After getting the truck home and parking it for a few hours I drove it again and it worked seamlessly. Anyone encountered anything like this. I'm used to the previous generation vortec engines but I understand this is a completely new beast.

check all of your intake hoses for a loose clamp, sounds like it is sucking air after the map sensor

Thanks I'll check those hoses. The oil pressure on these trucks are messing with me it will drop to around 18-20 pounds when the engine is warm I'm just not used to it and I'm not sure if it's normal

The oil pressure is normal. The general rule is 10psi oil pressure for ever 1k in rpm.
