Well I bought a code reader and the codes are from the upper O2's
P1035 - Upstream Heated Oxygen Sensor Heater circuit fault - Bank No. 1.
P1131 - Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 1
Mils were taken apart and done correctly for sure!
HELP!!
mils go on the cat monitoring sensor, the down stream sensor, not the O2 sensors
you need a new O2 sensor
and fyi you need working cat monitoring sensors also since the mil eliminators just block the computer from setting the two pre-cat codes P0420 and P0430
