Hi all,
THANKS for all the messages regarding my bucking, or stumbling, problem
while on the highway.  It hasn't happened again, tho I haven't been on the
interstate again either.  I received a variety of answers and thought I'd
summarize them for the list:  2 or 3 said to change the fuel filter and run
some premium gas; 2 said it might be early signs of ECU failure (please
gods, NO!); 2 or 3 referred to an auxiliary airbox wiring harness; 1 said it
might be the hall sender on the distributor (never heard of that before); 1
or 2 O2 sensor replacement suggestions; 1 temp sensor near thermostat; 1
cruise control problem (I don't have cruise); and 1 suggestion to clean the
carbon track in the sealed airflow meter.  I have dutifully saved all these
responses in case the problem recurs and I have to go to my mechanic.  And I
put a tank of premium, name-brand gas in the tank.  Will have the fuel
filter changed at my next oil change.

Hate to gush but this list is GREAT!  Thanks again.
