I am getting two DTC's on my 2002 X5 4.4i with 65K miles, P1159 & P1161. Both are fuel trim codes but the P1161 bank 2 code also reads " oil temp sensor". I replaced the Air mass meter as a first guess, and reset the codes and the light stayed off for about 50mi. Now it is back on again with the same two codes. Where should I turn next.
