Disconnected o2 sensors for leaded fuel to check if I have false knock, ok??? I can't find anyone that sells unleaded racing fuel so I can check if this knock is false or not. So I was wondering if I use leaded racing fuel, can I just disconnect my oxygen sensors jump on the highway and see if my knock goes away at WOT? or is this a bad idea, Can the racing fuel ruin something else? Can running WOT without the oxygen sensors hurt anything? I don't have cats by the way.

You dont need to disconnect the O2s from what I remember. It's just the cats that don't like leaded fuel as it gets them way too hot. I mean, other than the problems with running leaded fuel constantly, but that's not in question or an issue.

Running leaded racing fuel all the time will eventually ruin your O2 sensors by leaving lead desposits on them, but you will be fine to run it once or twice for what you're doing.
