good afternoon my name is ***** ***** I will assist
first, stop erasing the codes. it does nothing for the issue as it needs to be diaged and repaired.
there is info stored when the light is on. it will take a snap shot of all the sensors at the time the code set and techs need to look at that to help determine the failure. in your case, all these codes are related to running lean. I would start by checking the fuel pressure. low pressure from a failing fuel pump will set all these codes at one time. you can rent a tester at a parts store to verify
thats correct. thats why you need the fuel pump test kit. you will need to tap into the fuel filter to test.
