Cannot remove O2 sensor *

[Livolsi, Stephane]

I have to agree with all of Ameer's points except one...

Relative is....well....relative...

Unless you are willing to go non-OEM and hack some wires, the O2 sensor
for a 5k can't really be called cheap.

Also, Cat, when I did the sensor on my 87 5ktq and the 88 5ktqa, I found
it best to set aside some time and remove the aircleaner, and the big
metal pipe from the fuel dist to the turbo.  It just helps to have as
much room as possible.
On the 86 5ktq, I also had to cut the wires and use a regular socket.
The problem is that once you do that, you are committed and theres no
going back.  That O2 sensor MUST come out because there is not enough
wire to splice the connector back on.

HTH some and good luck.  It is worth the effort as I had much better
running and driveability on both my cars.
