It has kinda evened out a bit, I’m thinking there prob was a clogged injector, I’m now at about half a tank and it seems to be a little smoother and not dipping that low just a little bit but not enough to “shake” the truck like before. I’m gonna run another fuel treatment after this one and make sure they are clean. I’m gonna check the TPS tho, bc I still get minor fluctuations when the AC isn’t on a well but they are really minor don’t even notice it unless I’m idling for long periods of time.
