You need a repair shop to drive the vehicle with a professional
scan tool, for at least 25 miles
That way all the Emissions Monitors will run clear
If you fail to do that,your guaranteed to fail inspection
If any codes come back,then the vehicle has to be component
test & repaired
It sounds as though there was some pushing & poking, done by
I assume, a shop & parts changed,tested or in need of replacing,
who knows
You also will have freeze frame data at the time the codes are set,
to help with the diagnoses,IF-- you have a good shop to work on it,
so far that doesn't appear to be the case
I don't buy your hopeful rational --IF-- the oil has not been changed
(often)over the life of the motor,wrong oil used or the cam actuators
have failed,as is sort of where all this conversation has gone or
explained to you
If the cam timing is not correct,then yes, the oxygen sensor codes
may set- BUT- I don't buy the fact they go away & never come back
We could be here a long time,so I suggest you keep your line of
questions going at a repair shop. Their not wrong or far off,you just
need to understand how things work together in a motor or maybe
not play well with other parts under certain conditions

Unclip the 02 harness, then take out the 02 sensor. 5 minute job.
SOURCE: bank 1 burning to lean check engine light on flunked state emissions
It is a common problem, you will have to change bank 1, o2 sensor as it is covered in burnt oil and fuel telling the computer to run lean.
hope this help

Mass Air Flow sensor! Just remove your air filter cover. Go to Auto Zone and purchase some solvent. Spray past the air filter and it should correct the problem. If not, replace the Mass air-flow sensor. This is commonly mistaken for an oxygen sensor. Mine did this and I followed these steps and it fixed the light. BTW, the light stayed on for 5 years before I fixed it. Never hurt anything. It's normally something to do with emissions. Dummy lights. :)

it is probally due to an evap -code and never refuel with engine running go to a parts store and get the code and erase code and go to have car inspected right away and put a bottle of emission reducer in tank WITH 1/8 OF FUEL and then put it on machine and you should be ok

P0600 is the loss of serial communication link. Generally this is a problem with the wiring in the OBD-II or between the ECU and the connector. Of these is a fault in the ECU. Do you recive any other codes?
