Im fighting a misfire problem on my car and am getting an intermittent noise from what sounds like the HPFP on my 18 GT. Most times it’s there but sometimes it goes silent before coming back after a few seconds. I also took a datalog and was wondering if anyone with a better eye for it could take a look and give me some advice on what you see, right now the STFT and LTFT are very erratic and rich for bank 2 but sometimes they stay at 1. During the first part of the log I had an intermittent CEL flashing and then would go away. I recently found some loose bolts on my exhaust manifolds as well and tightened them all down. I’m also getting codes P0300 and P0303/5/7/8 and P0316. Thanks a ton for anyone’s help, my IMRC are also locked out for this datalog as well.
