Default "S" light flashing - '90 Accord

'90 Accord LX coupe, 4-banger, auto trans. This car only has 101K on
it and is in remarkable condition, always carefully maintained,
extremely reliable. Suddenly, the S light in the instrument cluster
is flashing. Reading the manual, the number and length of flashes
should indicate the problem code. However, it flashes repeatedly, for
as long as the ignition is on. This situation is not addressed in the
manual. Trans fluid is up, so I tried the one trick I know - pull the
fuse which will reset the trans memory - no change.

The symptom associated with this: Where this car normally takes off
like a raped ape, it bogs starting out in Drive. In 1st, it takes off
like a rocket. This first happened last week. The next time I tried
it, everything worked normally, and it left the line with plenty of
zip. Today, we're back to the flashing S light and bogging down when
starting from a dead stop. Once it reaches driving speed, it seems to
function normally, and based on the tach, runs at normal RPMs (no
apparent slippage). I'm stumped.

Has anyone experienced this, or have a clue what might be wrong?

Thanks,

Unc

You need to jump the two pins in the Service Check connector, THEN turn the
ignition on and count the flashes.

The Service Check connector is a loose plug (gray, I think) above the
passenger kick panel (the plastic trim under the dash, just ahead of the
door).

We determined that it's not kicking down into 1st at a stop, thus the
sluggishness starting out. I found a diagnostic machine we can put it
on today.

Thanks

Follow up:

Thanks, Tegger. It turns out the brain had an intermittent fart
problem, as occasionally, everything would function normally. We gave
it a brain transplant and so far, everything works as it should. It
better, considering what this kind of surgery costs.
