Hello I have an accessport for my 2018 mustang and I recently de-tuned my car from the stage 1, 93 octane back to factory, because I only had access to 87 gas, during the time (1.5weeks) that I’ve used 87 unleaded gas, I have thrown two faults, one is P0148, which is fuel deliver error, and the other is P018B which is a pcm error also related to fuel delivery, would the change to 87 cause this? I’ve ran 93 in it since I had it ( early 2019). Any advice or possible causes is much appreciated!
