Ever since my Magnum XL swap (and after the tune to go with it) I have had the occasional pending P0300 and P0308 - the codes never seem to go anywhere beyond pending, but this is concerning...in the data captured along with the codes, I usually seem to be running about 70, 1800-2000 RPM, open loop, load is not too high, throttle position is low as well.
I have heard broken IMRC shaft can cause this, or oxygen sensors going bad can do this as well. Car seems to have the occasional light stumble, which it (and my 14 GT, and my 13 5.0 F150) ALL seemed to have...
Anybody run into this?
