Default 99 Camry LE - 4 cyl, auto, 100000 mi, hard starting ??

My 99 Camry LE (4 cyl, auto) just passed the 100000 mile mark. For the
past few days, I have noticed that it has been more difficult to start.
Late last week, the engine would crank and start right up but it
wouldn't idle normally but rather it would just die after a couple of
seconds unless you played with the accelerator to keep it going. I
tried a bottle of Chevron Techron just for the heck of it after it did
this a couple of times. Now it seems to require that I hold the key in
"start" position cranking it over before it really does start & run.

Car has been regularly maintained (3K oil & filter changes, routine
maintenance on other items, kept in good mechanical condition,
etc......not a "beater"). Up until now, it has run fine (except for the
water pump dying & eating the T-belt, which seems pretty common on this
year/model ---- luckily it was just before warranty expired so they
covered everything).

I do not trust the dealer service dept. (Freehold Toyota, Freehold NJ)
--- they are very expensive, always want to sell you a "repair package"
of some sort (even though I do much of the routine stuff myself where
possible), and I'm not sure they really diagnose problems as much as
"shotgun" the problem.

Any suggestions from the group ?

Does it run bad to or just starting hard, if running bad try new gas, I
had gas so bad once it took nearly a gallon of alcohol to get it going
good. Or cold start valve, moisture under cap, bad coil, it is hard to
say if electrical or fuel related

Seems to run fine once it gets started......idles OK, runs smoothly,
doesn't die at lights, mileage seems fine, etc.

Don't think it is bad gas.....have already filled up tank again with
fuel from a decent gas station where I have bought gas regularly in the
past without problems (not that that necessarily means much these days,
but it's probably better than nothing :-).

Interested in exactly what you mean by "cold start valve" ? Maybe I
have heard of it by some other name, but don't think so.

As far as moisture under distributor cap, bad coil, etc.....don't seem
to have any correlation to damp days vs dry ones and so forth which
usually come to mind in this sort possible electrical-related ignition
pblm but once again I don't want to rule anything out.

I will check the service records and see when the wires were changed
last. I **think** that I did that awhile back around 60,000 miles but
will make sure. Maybe it is time ?

If you find it possible to keep the engine going by blipping the
throttle,..then one possibility is the dreaded "Idle Air Control" (IAC)
valve which lives in the throttle-body. This can stick denying proper
mixture for a smooth idle. To clean it,..remove the intake hose at the
throttle body. Get some quality carby cleaner and moisten a tooth brush with
it. Then gently scrub the area where this valve sits which has a small
square appearance on the firewall side of the throttle bore.

Take care to sponge the dirty crud outa there with a clean rag soaked
lightly in cleaner.

If you can use Google search,..its beneficial to pull-up previous posts on
this group on your prob.

Most permanent cure is to have the throttle body properly cleaned and
adjusted and the idle air control valve replaced.
That will restore operation to like new condition.
This topic has been discussed many times previously. You could try
searching the group for "IAC" (idle air control valve).
For several years, I found spraying emissions control safe carburetor
cleaner into the small rectangular hole at the bottom of the throttle
body opening (IAC air intake) worked well enough. Lasted apx. six
months, and had seen quotes for replacement over $250, but eventually,
at around 125,000 miles, that only worked for a week or a few days.
The factory service manual section for IAC removal references the
preceding section for throttle body removal. This section also
describes procedures for checking calibration of items on the throttle
body like the throttle position sensor and - sorry, forget just now
what they call it - the vacuum dash pot that regulates the return of
the throttle plate, as well as how to clean the throttle body including
the three vacuum ports that supply the EGR vacuum modulator.
In my case, surprisingly, I found everything they mentioned needed to
be corrected, so there was improvement in several areas with this work.
The automatic transmission seems to take readings from the TPS so I
noticed some improvement in transmission response - that is,
downshifting only just before full throttle - easily regulated by
pressing accelerator pedal fully to the floor or not. Not sure, but the
low end, just off idle seems improved too.
There's an adjustment with a vacuum line removed, setting throttle
adjustment to idle around 1,500 rpm, and I needed to adjust that also.
TPS was off by a few thousandths of an inch, but apparently is enough
to make a difference, since the specification calls for precise
calibration.
Also, the smallest of the vacuum line hose nipples was at least
partially blocked (judging by the dark brown or black goo that came out
after being sprayed with solvent and air pressure as directed in the
manual).
There was also quite a collection of dark residue at the back
(accessible only with removal) side of the throttle body near the PCV
port. Mine's a '94. Your '99 might be different, because I think I saw
the PCV hose routing moved closer to the center of the intake manifold
rather than right next to the throttle body as on mine.
In summary:
Simple cure - $2 of carb. cleaner, only need to remove 1 10mm intake
hose clamp bolt, whole process takes less than ten minutes. (spray
while engine is stumbling at cold idle to open airways)
Complete cure - remove, clean and adjust throttle body and replace idle
air control valve

you seem to have some good info from Daniel and Jason, but if all else fails
i go to Lakewood Toyota and like their service dept. their a bit pricey but
i've never felt like i was screwed. i have a "99 and an '02 camry and have
been to the Lakewood service dept. a couple of times and don't feel like i
was screwed. they are a bit pricey, but it is a dealer.

good luck..........

mike..........

Many thanks to the group for the various replies. As suggested by
several helpful folks, I investigated the topic of Toyota IAC on Google
and ended up carefully giving mine a couple of thorough shots of cleaner
(along with the throttle plate, which has been known to get sticky a
couple of times in the past for me). Although I was tempted to use a
spray can of carb cleaner I already had on the shelf in the garage, I
ended up buying a spray at Pep Boys ostensibly intended for just this
purpose [cost a bit more, not too much, and the can said something about
being safe for the coatings on the parts involved so I figured what the
heck]. The toughest part was getting the big black air intake tube off
of the main throttle body once I had loosened the screw clamp ......
boy, it was really on there! But I did keep at it, and after a minute
or two had gently worked it free with no harm done. In any case, the
problem has (at least for now, about a week later) completely
disappeared; while I understand that such relief is more often than not
temporary, so far so good and certainly cheaper than paying dealer big
$$ for cleaning, new IAC valve, etc.

Hello,

Can you please tell me about the Can you bought at pep boys? Brand,
price etc.

I have '99 Camry as well close to 100K miles. I used to clean the
Throttle body myself using STP throttle body cleaner and the results
were good. Last time I cleaned is about 8months ago.

Offlate when I start the car the engine starts right away but it seems
to hesitate for about 0.5 sec. Just seems like trying to shutdown. But
car starts and I can drive very well without any problem. May be time
to clean the throttle body again. But I used to clean earlier only when
the accelator pedal sticks and each time I find black gum at valve.

TIA

It's a grey spray can marked "Gumout Air Intake & Throttle Body
Cleaner". I don't remember the exact price (and nowadays everything is
done with the scanners so prices rarely if ever get marked right on the
item) but I would guess about $5 or $6 at most.......like I said, more
than the plain old carb cleaner sprays which were only a couple of bucks
per can but not really that expensive.

Yes. that sounds ***exactly*** like my situation. Very pleased to
report that it's been several weeks at least since I liberally used the
Gumout spray & a rag in that general area [with special attention to
getting the solvent down into the IAC and its opening into the throttle
body area in front of the plate] and have not had any recurrence so far.

Very interesting!!

I will do the cleaning this weekend. I am somewhat familiar with the
procedure. Dealer once offered to clean the entire throttle body in a
solvent for $50 but I declined.

I used STP cleaner bought at autozone. the sales guy said that is
better than Gumout. Well I think they both are about same.

Thanks
