2006 Buick Lacrosse CXS - 3.6L

Had a miss, code PO301 came up.
Put fuel injector cleaner in full gas tank.
Drove about 3/4 of a tank, miss seamed to be getting less.
Checked codes, now Code p2097 came up.

Should I just keep driving until the gas tank runs low and try another can of fuel injector cleaner?
OR ?

THANKS

Hi there

The misfire is likely the result of a bad plug or ignition coil. This will spur the P2097 code as there is raw gas going into the catalytic converter. I would repair the misfire then clear the codes to solve the problem.
