1990 Cherokee sputters at throttle
my Jeep idles fine but the second you give it throttle it’ll sputter/Bog. I’ve replaced the upstream o2 and the intake gasket. Can’t find a vacuum leak. Not sure what to do.

You can check out cruiser's info pages that have a ton of great info on your Renix Jeep - www.cruiser54.com
I'd do that and check your TPS (outlined at the above site) and while you've got the hood open, clean and tighten all your grounds just for good measure (also outlined at the above site).
