There are 2 sensor for my 750...one is exclusive for the instrument cluster and the other one sends data to ECU....so my ECU is getting wrong data. No way I could fix air/fuel mixture then.
Looking back a month ago I realized the first symptoms of a bad sensor...upon start I began to feel a strong fuel odor and then my car's idle went crazy....How do you guys name that kind of thing? rough idle? It was varying from a 600 to a 1000 and the back to 600 or 500 revs and would shut off the engine sometimes.
Let's see if I can fix things up now.
