The day after I took my 1998 Olds Delta 88 in to a local metro Atlanta
( Buick/Pontiac/GM dealer for the fuel rail / regulator recall in my
check engine light came on . I had it scanned and got the Code P0171 (
The fuel system of bank 1 was too lean "). Was this jut a co-incidence
and not related to the repair . What is likely actually to be wrong
and waht is the fix ? - thanks
I couldn't find any information on a recall for your vehicle, so I'm not
sure exactly what they did or if what they did could have caused this
problem. The diagnosis for this code is pretty extensive and requires a good
Something that stood out in reading the diagnosis info, is the fuel pressure
could be too low. If the dealership changed the regulator, maybe it's
faulty, maybe they didn't connect the vacuum line to the regulator, maybe
the vacuum line got damaged during the repair, etc, etc.
Take the car back to the dealer and let them deal with it.
