>Will a bad O2 sensor make the car hesitate during heavy acceleration? car hiccupped at 3000 o2 solved the problem...

I'm convinced the best indicator of a slow o2 (new o2's respond very quickly
to changes in conditions) is an oscillation in the idle rpm.  The slow o2
can't send info quickly enough, and the computer is "chasing" old
info....hence, oscillating idle....

When I see this, I just get a new one....
