Jerry,

I had an unstable idle that surged back and forth in an 87 that I traced
back to a small crack in the rubber elbow in the intake. It would take

in

too much air that would lean it out, then the computer would correct and

the

whole thing would start over again. Kind of a computerized version of

PIO.

Check your intake.

On another note, your Tailwind newsletter was mentioned in the letters

to

the editor section of the April Sport Aviation.

I agree with Barry. Check your intake hose.
My 86 was doing the same thing and I found the clamp that holds the intake
tube to the throttle body was a little loose. Just enough for air to leak
past and cause the problem at idle. That airflow sensor in there must be
real sensitive.
