My cel came on earlier I had 2 codes bank 1 running lean and bank 1 O2/ lambor sensor low voltage I did a live data stream on my diagnostic and the O2 sensor fluctuates between 0.00 and 0.97 even on idle it doesn't increase or drop when u rev it it also nearly stalls when stopping sometimes is it safe to say I need a new 02 sensor ??
