Hey i've found 3 different explanations for this code so I want to know which one it is,
its p1151 on a 325 e46 coupe
The ones on this site says:
P1151 O2 Sensor Heater Circuit Signal Intermittent (Bank 2 Sensor 1)
P1151 Lack Of HO2S-21 Switch Indicates Lean
P1151 ETS Main Accel Position Sensor 2 Malfunction
So which is it guys??
Sorted the misfiring problem and shivering at idle,
had a look at intake pipes and cant find any big cracks.
