RE: URQ sorting out



Steven,

You mention IST documents, can you elaborate more on this?  I am going to be
taking possession of an 82 this weekend and am trying to gather as much
information as I can get...


Thanks,



-- Jim

		... this is a big indicator IMO ... If you can see the
resistance of the

the ECU react to
		them in changing the duty cycle that is a problem.

		IME the OXS is actually pretty easy to get at with the
headlight removed and
		the lower part of the airbox out ... which is something I
can do on my car
		in a few minutes ... perhaps its because of the Cibies ...
but based on what
		you are now seeing, it sure seems to me that replacing the
OXS would be a
		waste of time (and perhaps money) at the current stage.
