OBD codes P0016, P000B --- 93 octane
2011 Grand Cherokee Laredo 5.7 Hemi
I filled my tank up with 93 octane, for the first time that I
recall, and the next drive I got the engine symbol with those
2 codes and some associated monitor codes.
I think this is just a misfire, and the check engine symbol,
or Mil codes symbol, or whatever it is, went away, thank goodness!!
But, my question is, IS there anything about high octane
gas that is forbidden, or problematic, or anything??? Thanks.
I'm very sceptical(sp) about this MDS system and how robust it
is going to be. As I was doing my first drive after the above,
the cruise control would not engage, and it didn't seem to have
normal power. The ECO indicator never came in view, and I
couldn't feel the wierd/noticable shift between 4 cylinder to 8 cylinder mode.
