P0134
Hey all,
searched for a case similar to mine but did not find the same issue. All the threads I read for this code is usually recommending to replace the front O2 sensor and people are having bad drivability. Not so much in my case, so I am wondering if I am good for now. Basically I am tuned for E85 and had to fill up with 93 as an emergency. That’s when I started getting the code. I am now gonna have a second map tuned for 93 so I’m still driving around with gas in the car. Is a car with a e85 tune running 93 gonna throw this code and will it go away after the tune?
p0134 is sensor circuit, no activity detected

I am unsure about the code but running the car on an E85 tune with 93 is going to be silly rich.
I would probably get the tune or fuel situated and see what that does for the code.

Sounds like running 93 with an E85 tune fouled up your front O2 sensor. As the other guy said, put E85 back in then if it doesn't fix itself, you can pull the O2 sensor and clean it with some fresh gasoline and a soft brush (assuming that it needs cleaning after you visually inspect it).
