You said, in part:  "

"Since you replaced the multi-function sensor, I would start with that as the
likely culprit.  Even new parts sometimes are bad or fail immediately.
There should be some basic tests for the multi-function sensor on the SJM
web site.  If the ECU is getting a hotter temp than reality, it could be
confused into a lean mix.  Sorry, I forget if the ECU gets its temp from the
multi-function or one of the other sensors, so you may need to look that up
on the SJM site, or someone with a more recent memory might chime in."


The MFTS doesn't have anything to do with the FI.  John
