well i have had a stumble off idle for a while and car just felt sluggish so unplugged my 02 harness and man my car feels better while driving but it loads up idleing because the o2s cant control the fuel mixture at idle. i think i have a bad o2 or one is wired up wrong because i have 1 universal 02 because my harness was melted before ! any thoughts......

Your fuel mileage will be horrible, but your W.O.T performance will be the same. Might have some small driveability issues also.

Do they get contaminated only when plugged in? I always thought that they would get fouled by race gas even when they weren't working.

Im sure the race gas continues to damage the sensor part but without them plugged in the computer sees an error and trys to compensate or whatever. Once they get messed up there done for atleast as far as I know.
