At the first time my check engine light comes on I unplugged the negative terminal of the battery, I repeated this procedure 2 times at the third I have diagnose it by the OBD2 it gives me
P0301 misfire1 cylinder1 detected the technician erased the error and then I bought NGK spark plugs and I replaced them all I see the old ones with a bad condition ( approx 86k miles ) then I have unplugged the negative battery terminal to turn off the light after that when he comes back on I get the car to another technician to diagnose the error with his OBD2 it gives
Again
Saved errors: misfire1 cylinder1 detected (new codes)
new codes: error1 2 3 4 5 6
He tells us this errors are the result of removing coils and he erased all errors
Then he tests the EGR it gives 0 and with acceleration gives (-/) (live data)
The next day the check engine light comes back on again and it stays on until know
What should I do? Plz help me and thank you for the first answer
Attention : the valves are always noisy should I adjust them?
