Default 1997 Camry LE : Vehicle refuses to idle

1997 Camry LE 4 cylinder
149,000 miles

All regular service performed, and I clean the throttle body every third oil
change. Carbon deposits seem to like to collect there and stick the throttle
if I don't.

Started the car yesterday. Everything was normal. Drove it a 1/4 mile to the
gas station. I topped it off with 7 gallons, replaced the cap and restarted
the car. The idle was rough and a little low, but it stayed running. Put it
into drive and immediatly brought it back to the house. In both park and
neutral the vehicle displayed the same horrid idle. I stopped the car, made
sure I put the gas cap on (which I had), popped the hood and inspected to
see if the intake hose had somehow come off or the MAP sensor had somehow
become dislodged or disconnected (happend in my 95 Mustang GT's MAF last
week). All being normal, I tried to restart the car. I got nothing. The
engine fired, revs rose to ~1000 RPM, and when it fell into idle position it
just kept falling and died. The engine runs just fine if I apply slight
pedal pressure; no hesitation, no roughness, just fine. When it is running
with slight pedal pressure, the car is displaying no warning lamps.

This morning I pulled the intake hose and checked the throttle body for
deposits. It was still pretty clean from the last time I had done it. I've
looked into it, and heard that the Idle Air Control Vavle also likes to
collect this junk. Not having the time this morning to remove the throttle
body and get the valve out, I sprayed a little carb cleaner in there in
hopes that it would free the solenoid (is that how it's operated?), but no
luck. Either it didn't free it, or it's not my problem.

Any ideas guys? I absolutely love this car. I have two other vehicles with
which to go about my life, but it's like an old, trusted friend. It's never
let me down, and I suppose that's why it's got me so frustrated. My Jetta's
second home is the service bay at my local dealership...

Thanks for the advice!
Jon-Patrick

It's time to visit the dealer, they'll know what to do. Take it to an
independent shop and they'll have you dropping $200 on tune-up crap in the
hopes that will solve the problem without any diagnostic work. $149,000
miles! You've gotten some terrific service from this car.

OK, if you keep your foot on it till it warms up, will it idle then?
Does it only happen when cold?

If so, I'd still guess it's the AIC, and cleaning/replacing the valve
will fix it.
