Re: V8 Codes and troubles

[Roland Broberg <broberg@execpc.com>]

O2 sensor did it for mine.  Major difference was immediately found.  Most
noticeable was the long uphill onramps to I94.  The surging was very pronounced
until the O2 sensor change.  My V8 is very sensitive to fuel, though.  I use AMOCO
or Philips 66 93RON.  The AMOCO is most stable of the two but the P66 is cheaper,
usually.  Anything less than 93RON and the V8 does not like it.
