ecus really only learn the long term oxygen mixture trims
if u were an ordinary joe blow or a granny driver u would never
realize an ecu reset when it comes to performance
if it feels like a miss then leads and plugs maybe
remove injector at a time and see which cylinder
makes I difference in revs
also remove exhaust and re drive
maybe u have blocked exhaust

but most common is plugs n leads
it's hard when the scanner doesn't say much
u actually have to use yr head
these are the jobs I always loose money on
