Re: <E28> Hesitation Problem

[George Ax <George.Ax@xxxxxxx>]

Check the distributor and rotor.  Mine was hesitating to the point of
lurching to a virtual halt before resuming acceleration.  When I pulled the
distributor and rotor, they were badly burned.  It appears that the rotor
was arcing where it wasn't supposed to (due to excessively high resistance
I imagined - so I sucked it up and replaced the ignition wires and sparks
also).  The car is accelerating MUCH better and more smoothly now.
