hi, chk eng light ON, code is P0173... some fuel trim malfunction, bank 2 ?!?!
on a 2001 s500 , 83K miles... car idles fine, goes fine...no issues...
i reset the light but it comes back on after a few cycles...
have to do calif smog and may not pass, if the reset time doesn't cycle out of memory... passed 2yrs ago with same issue but never 'fixed it' then...

what is a potential issue with above code? fix? cost ?

thanks guys,

james R
