I have a 2014 Silverado 1500 6.2 high country. I have a rattle in the front passenger side, seems to be under the hood but I cannot locate it. It’s rattles from around 1700rpms to 2400rpms. It doesn’t happen all the time but it’s super annoying. Has anyone had any problems like this or can point me in the right direction? I checked the exhaust and everything seems to be tight. Thanks
