Disconnected my O2 sensor this am as part of my ongoing search for cold driveabilty problem. It made absolutely no difference as far as warmup driving (O2 sensor not in loop afaik), but when warm car feels like I put another chip in it (already has a Jim C). Better, smoother pickup from low-midrange, car peppier in general. Idle now ROCK steady, instead of "normal" slight fluctuation from 700-800. So am I in grave danger of gumming up my cat, plugs etc? Doesn't feel/smell too rich to me... Or I am I just in danger of going below 10mpg in the city?

Seriously, If this is just a bandaid fix for another problem causing car to run too lean with O2 sensor, any ideas? Air leak, misadjusted AFM, bad DME??
