Hello everybody, I am looking for the Infiniti G35 with engine VQ35DE. Last time I saw that one, but he has a problem. On the back of the engine can be heard the loudest another strange noise (from 0:50), I recorded video. Next thing, Lambda was changed, but after about 60 miles "Service Engine Soon" returned. I plugged consult and shows lambda error in front of catalyst. Is it something serious? Rod bearing? Timing chain? The car has driven 85000 miles. I'm sorry for the mistakes, but I'm not from England / USA
