Default cold start problem

Hi Experts,

I have a Toyota Camry LE (4-cylinder) , 1997 model. From last few
days, I see COLD START problem in my car. In the morning, when I
start the car, it does not. As an alternative, I put my leg on
accelarator while starting the car so that it gets started. After few
seconds, I take out my leg from the accelarator pedal, and drive the
car.

I am not sure, this way of starting the car as an alternative is good
or not. But, I would like to go for permanent solution to this one.
Thanks in advance.

Any inputs or feedback would be great.

You can see the earlier threads here are from 2001, on the same topic
-- so it's been going on for a while now.
A few light sprays of emissions control safe carburetor cleaner in the
small rectangular hole at the bottom of the throttle body with the car
idling cold will solve it.
Search "IAC" in this group for more.

I own a 97 Camry 4 cylinder myself and the spray-out method didn't work for
me. If the pintel is stuck, there's no guarantee it'll unstick. My
starting problem was intermittent, then I had Firestone spray out the IAC
and the problem became permanent. Took it to the dealer (at Firestone's
request), the lousy IAC was diagnosed as bad. $385 later with a new valve
installed, the car fires right up and will do so for YEARS. It's your money
and your call. The IAC was $222, installation was $140 so you're looking at
some real money here.

The dealers do ALOT of these, they knew what to do right away and did it
right. You might want to try a fuel induction service. That should clean
everything out in there. The problem will probably return in 6-9 months,
but it'll buy you time if you want to trad the car away.

Didn't want to say anything, since you had already done this, but if I
remember correctly Firestone emptied something like two or more full
cans of cleaner and still failed to improve anything.
Personally, I would never take my car to Firestone. Occasionally you
can find a great mechanic at an unlikely place, but generally, my
experience has been that they are less than completely honest or
competent.

I started working with cleaning the idle air control valve because the
prior owner already had the dealer replace it - as you say not
inexpensive, and the problem returned.

With just a very light spray of Berryman, the problem can be corrected
in a few minutes at virtually zero cost, with a single 10mm wrench, by
removing only one hose clamp. The old IAC valve, works beautifully
now.

Firestone had no business dumping that much cleaner through the
throttle body. That kind of behaviour can create additional problems.

The Firestone tech said that they sprayed it into the IAC opening until it
ran out clear, so the fluid was running out of the housing where they were
seeing it flow They probably removed part of the fitting to spray it out
real good...whether they broke the pintel is hard to determine. They made
a good faith effort and were honest enough to throw in the towel when it
went over their heads. I have no beef with them.

I've seen other posts where they recommend doing a "bench cleaning" of the
valve. Another post claims that you have to disengage some kind of motor
from the throttle body before spraying out the IAC. Everyone agrees it's
a band-aid repair...kind of like repairing your radiator by adding a sealer.
Cheap can be good...but in the long run?

There's all sorts of theories..... Another poster says Toyota techs won't
bench clean the IAC's anymore because it'll just keep happening.. I look at
it this way, if it took six years for this problem to develop on my Camry,
it won't be back for a couple of years at least, if it does, I get a fuel
induction service to free it up for 6 months which will be just long enough
time to shop for a brand-new Chevrolet. The only shining star for Toyota is
the great service I received at the dealer, expensive yes, but well worth
every penny.

Fuel induction service cleans the fuel injectors. This is not related
to the idle control valve.
Second, I suspect you're overestimating the utility of the IAC valve
replacement.
Generally, the electric step motor, and wiring do not go bad. If they
actually did test faulty, then I agree to replace the valve.
As your engine ages, oil vapor through the PCV valve may increase,
which means you will not get the same life out of the replacment IAC
as you did when the car was new.
But, my friend, you are free to follow your own heart. If you feel
better about paying to have the IAC valve replaced periodically,
that's fine with me.

I guess misinformation is everywhere out there. Visited a mechanic at an
independent import repair shop about spraying out the IAC and he said his
fuel induction service cleaned the IAC and injectors and I should give him
$139 to do that. Walked out on him quick, the dealer only wants $119 to do
one of those services.....making me even more impressed with my local
dealer. Doesn't anyone else out there wanna weigh in on this with some
opinions. Maybe Dan and I are both wrong and we should just smack the valve
with a rubber hammer.

Idle AIR control meters only air - cleaning fuel injectors wouldn't touch it.

Default Midas defines Fuel injection induction......

Fuel Injection Induction Service Basics:
The difference between a dirty and clean fuel injection system can be
measured in tangible symptoms such as: hesitation, rough idling, engine
run-on, pinging and knocking, poor acceleration, lost power and performance,
and high exhaust emissions. This regular maintenance routine will help a car
run more like new.

What This Means:
By cleaning the fuel injectors, intake valves, throttle body, air intake,
cylinder heads, pistons and rings, lost performance is brought back. The
engine will be cleaned at these points, allowing fuel to be processed more
effectively.

The Results:
Horsepower returns as performance is increased. Exhaust emissions and foul
exhaust odors are reduced while hesitation is eliminated and gas mileage
improves.

Just my personal opinion, but I wouldn't go to Midas either.

Or Pep Boys.

Use the Toyota dealer, or see if you can find a qualified independent
mechanic who specializes in Toyota, or learn to do your own work.

Naturally, Midas will justify and sell the services they provide.
For example, I hear their lifetime free brake replacement pertains
only to the pads themselves, excluding additional labor which is
always required and adds substantially to the cost.

If you want to clean the injectors and fuel system, read the technical
information at:

http://www.redlineoil.com/products_fueladditives.asp

I've been to mechanics who have left the cotter pin out of a lower
ball joint causing the car to come crashing to the ground months
later, fail to drain transaxle oil properly, leave spark plugs finger
tight, over fill oil by seven quarts, leave newly installed muffler
hanger rattling against the frame, rebuild a manual four speed
transmission so it only shifts into three gears and the clutch
improperly adjusted, -- and I'm sure there are others.
If I understand correctly, you just had a bad experience with
Firestone, paying them and then going to the dealer for another $388
repair. I wouldn't expect Midas to be much different, but these
franchises have been in business for many years, lots of people must
be using them, but I think you can do better.
