92 Accord with 200K miles, runs great, want to drive forever. Problem is
it ocassionally will
not idle worth a darn, drops off and stalls. Will go away for months then
return. Have factory m. and the idle woes all should generate a trouble
code- none present. Any advice fellas-suspect a vacuum leak somewhere but
can't seem to find one. The car runs excellent- 200psi on all 4 cyl, this
things runs better and better, except this annoying, intermittent problem.
Live in the SE so I doubt water in the gas. Thanks everyone!

Does the stalling occur only after the car has been driven
20 minutes or so? If so, I would suspect the ignition coil.
How old is yours? Is it OEM?

Do check the level in the cooling system reservoir; top off
per the manual; purge of air. Forty minutes may be required
before the fan comes on twice during the purge procedure.
(Have you had any work done on the cooling system recently?)

The EACV (a.k.a. IACV) is also a candidate here.

Exact conditions under which it happens? Cold, hot, warming up? Length of
time it will idle badly before dying? What happens if you try to help it
with the gas?

An air leak will cause elevated idle or fluctuating idle. You do not have
an air leak.

Problem usually occurs when car has warmed up and its hot out. The cars a
stick- so I can come to a stop while revving the engine some- scary
though. Will shut th ecar off and it runs super for months?! Last time
it was messing up
when first started. The car will start up with no problem. Have changed
out he usual failings on the car main relay, distributor recall, radiator,
master cylinders and booster.

I recently experienced similar problems with my 1988 Accord LXi (original
owner, 185K miles). Distributor vacuum leak detected, repaired: no
improvement. Original fuel filter replaced: no improvement. Air (probably
from failed hose repair prior year) purged from cooling system: no
improvement. Main fuel relay intermittency detected, component replaced: no
improvement. TW sensor intermittency detected, component replaced: problem
solved.
