I get this about once every other month, any ideas on the possible causes? Has anyone had this experience?

 

Check the fuel regulator.

 

Thanks. I'll check the fuel pressure, then the HO2S1 and HO2S2, then the Vacuum on the evap can, as per the manual. I was kind of hoping for a response from someone who'd had similar codes and repaired it, but the stock response is still appreciated.

 

Did your ever fix this?
