Question about 2002 BMW 3 Series
Check engine light on. Running lean and misfire codes on all banks. o2 limitation code and cat deficiency code .I HAVE replaced fuel pressure regulator /fuel filter and changed spark plugs and cleaned the injectors so far . The light is still on
It could be your exhaust sensor. If it is not sending the right information to the computer than the computer will adjust the tuning to suit.I hope this helpsregards
