For the chap who has the '95 Pickup; if he used the supplied BOSCH 4-cavity interface connector, it's quite possible that the lack of continuity is in THERE. The connector is impressive looking, but has terrible connection. Try a direct splice with soldered connections & shrink-tubing.

Now for mine - the factory apparently rounded off the 12mm nuts on my O2 sensor studs (I'm the original owner), so I get to "crack 'em off". The question... are the nuts a special type?, also - as the studs appear NOT to have threading on the exposed 1/4" (above the nuts), are they standard thread or some special threading?

Hi there,

This no thread section is just the lead in, it is a normal thread.

The nut should just be standard R/H?T nut. The stud has this blank thread section as a lead in, there is plenty of thread below. this is a std metric thread, be it fine or coarse it will be a standard thread.

mark.
