2013 bmw x3 engine change
Hello new to forum ....I have a Bmw x3 i28drive with n20 engine. Timing guides went kaboom and I put a 40,000 mile engine in it from 2015 early model 428I N20 engine...Runs perfect very happy however engine light illuminated and throwing code P0101 lean fuel mixture or vaccum leak. Vaccum pump is working no hissing sounds no problem with engine idle or anything. I would like to fix this light and wondered if anybody else did this...Love the vehicle put a lot of money in it before engine went...could do the LTFT AND STFT test to check but unsure how to do this..what type OBD tool does this??

Did you do a smoke test? Just because you don't hear hissing, doesn't mean there's not a leak
