P0171 System too lean is a serious issue on a petrol car and can cause permanent damage to the car (petrol car too much air , higher temperature), fix it !

I'm already checking - Lambda working fine. Something is wrong with error checking after playing by some "professionals" with resistors on lambda wires. Car working fine so i want just delete this dtc from ecu.
Can you help me?
