Point of O2 sensor?...

[rhock99@epix.net (Ryan H)]

No, Collin suggested disconnecting O2 to see if the O2 doesn't work... sorry for the confusion.  Should it run badly without the O2 sensor connected?   Also, how would I diagnose a bad hall sender?... mine's not cracked, and there's no oil leaking around it (dist. & rotor are new).

----------------------
I'll fix my car, even if I have to replace every part in it... and since the problem will be the last part I replace, I'll have a brand new car when I'm done!
