That twitchy foot feeling might be attributable to a poorly adjusted
throttle position switch.

> With all the talk about the 'Digijet Stumble' -- a problem that has been
bugging me for a while -- I decided to try disconnecting my O2 Sensor (Bosch
one wire type about 4 months old).  The engine ran great when cold --
nothing new here.  When it warmed up the off idle stumble was not present
BUT there were some odd RPM fluctuations at what should have been a constant
speed (like my foot got twitchy) and the idle went to crap.  By the time I
pulled into the parking lot at work it was barely idling.
