I need a little help identifying an issue. My car more often than not runs lean around 4500-5000 rpms. It got some bad e85 a while ago, so pre and post filters were changed, as well as the fuel pump. The car ran fine before the bad fuel, so I'm thinking the issue is still fuel related. At about 4500 rpm the wideband will go up to around 12.0-13.0 and the motor sounds like it's running out of fuel. It runs completely normal otherwise. Only thing left to change is the pressure regulator and the injectors. Before I drop even more money, I'd like to hear yalls thoughts. This is all on 93 with the correct 93 tune btw. In the first video, the issue occurs, while in the second, it doesn't they were taken within a few minutes of each other. I'd also like to point out that there have been no issues with the car before the bad e85 was pumped in it.
Fuel setup is:
A1000
-10 feed
