Do you need em ? how is running without them going to affect things ? would the car have needed a re-flash to run without them?
it seems to have been running ok, and pulls as hard as other 3.0s i have driven
crawling around under the car today starting replacing the guibo and i noticed a couple plugs on the g'box x-member with no wires coming from them. looked further down the line and the wires coming from the oxy sensors have been clipped and ziptied out of the way.
