code 12 only means you hade the battery diconected within the last 50-100 starts
so thats not your problem ,
with the little info you have given i can only sugest you check your fuel presser first
then let us know .

25 is your IAC , Idle air control, motor circuit .
could be damaged or mite just need cleaning out
that will explain the rough off on idle.
(55 is just the end of mil display)
check that you have good battery connections
and check your ALT for a good charge for good voltage and amps.
