Hi.

My car has developed a problem that I cannot find a solution to. It is
a 1991 Honda Civic Special Edition (Canadian Model), 1.5L, 180,000kms.
It is basically a DX with power steering and no AC.

To the problem...

The car stalls. It only stalls when warm, and only when coming to a
stop. To be exact, only after coming to a stop. Sometimes it does not
stall, but almost stalls, then recovers. Sometimes is almost stalls,
then recovers and over revs, then almost stalls again. Back and Forth.
Sometimes it fixes itself, other times it stalls. Most of the time,
it immediately settles down to idle as it should, but at least once per
trip it will act up. It will sometimes stall with a gentle throttle
blip at idle as well.

The problem first started occurring when I had to back the car down a
hill into my driveway. The problem continues and seems to get slightly
worse all the time.

The car always starts immediately after a stall. The check engine
light is not on, and the ECU is not showing any codes. I have cleaned
the injectors, replaced plugs, rotor, cap, fuel and air filter. Every
time I do something nice for the car, it behaves for about one tank of
gas, then it acts up again. It happens when it is hot out, and when it
is cold, on summer gas and on winter gas, full tank and empty tank. On
high octane and low octane. Even though it happens regularly, I cannot
force the event to occur.

The dealer says they cannot do anything unless it stalls for them.
Does anyone have any idea what might be the cause of this? With this
exception, the car feels great and the engine is strong.

I appreciate any help or suggestions.

Thanks.
