Default Camry '95 - idle speed running down

I have an occasional problem with my '95 camry 196k miles.

When I stop on the red light and keep the car on drive
with brakes engaged I see rpms drop a lot, car almost
stalls. I need to switch the tranny to neutral to prevent
this and rpms go back to normal then. It does not happen
all the time, I could not figure the pattern yet but
usually when it happens the car is not warmed yet.

I have not changed spark plugs yet, I am going to,
but my worry is that the problem is in the tranny.

What is the common source of such problem in camrys ?

Could simply need a tune up, or ignition timing is off , you have
removed the pan and changed the transmission oil filter im sure.

Have you ever seen how thick the oil is when it is really cold out. It
takes a bit more effort to pump thick oil through the engine. I also
have noticed this lately during cold morning with lights one
(alternator load), Defroster (AC is on), and then I hit the wipers to
remove the moisture on the outside. Boy do those wipers move slow and
you can get the blower speed drop. I usually turn off the defroster
until I get moving again, because the AC is the largest load, and it
would be silly and perhaps dangerous to turn my lights off. You can
check your alternator, regulator and battery (which is like a
capacitor when the engine revs are low). I replaced the battery with
a cheap one (the minimum on the CCAs) and I am positive that this is
the reason for my engine load increase. A cold car will usually
perform a bit out of tune, because it simply isn't at operating
conditions, yet. I am not saying neglect any symptoms, but in the
winter I also notice cold running conditions that quickly go away
after about 1 minute or so. Winter is brutal on cars. I never let it
idle to get fully warmed up. Just jump in let her idle for 15 seconds
or so and drive her gingerly for the first mile or so. Lot's of
different opinions on this one, but I think cold idling just loads
them up with carbon. This 4 cylinder really warm up fast, too. Just
remember, running conditions for a tune up are usually performed at
normal operating conditions and if you don't have symptoms when it's
warm, then it is anybody's guess.

First - I am in West suburbs of Chicago - there is no winter here yet... :-)
Yesterday it was 65F, very sunny, beautiful day... Today it is still 60-tish.
Second - I own this car for 7 years, I know when it does something odd.
This is not your regular oil thickening when the car is cold - my car has never
strugled before like you have described - maybe when there is -20F outside,
but not in fall at 60F. The battery is almost new, car starts like a charm.
No problems with sluggish wipers or dimmed lights...

I probably misled you guys saying it happens only when the car is cold.
I should not say this. It really happens when I start the car for the 2nd time
after a very short trip. So true, car is not fully warmed up yet... but not cold.
Let me give you a scenario - video rental store, couple of blocks away.
I went there once, so I started the car, drove for 4 minutes, turned it off.
Then went inside for 2 minutes to drop the tapes (they are in reconstruction
and dont have the outside car-friendly drop-off box) and went back to the car.
When I started car again and departed home, next red light I got the iddle issue.

So as you see,
this is rather a problem related to starting a not fully warmed car.

That is my question... is it simple tuneup (whatever it means for my car)
or something worse, ie automatic transmission problems...
Remember, the way to bring the revs back to normal iddle speed is
to shift from drive to neutral/park. It looks like the engine has not
enough power to fight the resistance of transmission in drive and
with breaks applied.

> you have removed the pan and changed the transmission oil filter im sure.


No, I have not done this yet. And my car is due for the transmission flush.

If your ignition coil is under the cap that is a classic symptom of oil
on the coil shorting out after it has just started to warm up but goes
away after 30- 60 minutes. Removing the cap and cleaning it good usualy
fixes it, or a loose distributor cap alowing in moisture. Anyway you
probably need a complete tune up as it could be a few things, even bad
gas.

You mean trans drain, don`t do one of those Power flushes.

I have done the flush two, maybe 3 yrs ago and I was happy about it.
Now I will do regular drain.

Two things control the cold idle speed:
1) coolant temperature sensor
2) idle air control valve

Try spraying some TriFlow into the small rectangular opening at the
bottom of the throttle body to free up the idle control valve.
