I did the same thing. It ran like my Msd or distributor was taking a dump but after I checked all plugs firing and not breaking up I started looking at fuel. I simply looked down the throat of the tb and seen one whole port was dead and not squirting fuel. I swapped the injector thinking it was bad but it didn't leave that port so I knew it was signal. I then put my meter on it and seen it was not outputting a signal. Injectors was fine. The funny thing is when I data logged a pull it showed the truck was running fine of afr and fuel because the system was strong enough to correct the issue afr wise but I was about a 100hp down. Basically driving a V6. Hope this helps
