ok i have a 2007 saturn outlook and only durring the winter does this happen.
i get a code actualy 2 codes saying running lean bank 1 and running lean bank 2.
i took it to the shop they had it over night and they did a smoke test to the vacume system.
nothing code was gone they left it in the shop overnight so i think becuase the vehicle was warm it went away.
again the temp has to be below 40 deg farenhight.
i changed the throttle body and mass air flow sensor but also to no resolve same codes.
i am now considering changing the fuel pump.
i am bitting at the bit becuase it seems to go away durring the summer.
i also notice durring the winter a prolonged cranking period.
where the engine strugles to start.
again i have had the vacume system tested for leaks and no prevail.
i am also noticing some sluggish behavior.
and to top that when this code pops up it turns the stabil track off.
definately related but the track only reports that it is off due to an engine issue.
any advise would help.
