i was trying to get the mixture set on the 4kq  last night and hooked up
the multimeter to a ground and used and jumper to connect
to the o2 sensor, i was originally getting a littler over 0.9v at wot, and
0.8 at idle after a bit of tweaking it seems to run best with a variance
from 0.4 -0.8 i leaned the mixture a bit and at wot now i get 0.84 seems to
run smoother while cruising it seems to reside between 0.5- 0.7 which i
assume is reasonable.

oh, i was checking DPR current and it seemed pretty fixed at 9.73 is this a
bad temp sensor since the o2 sensor is relatively new and seems to be
functioning correctly?
