Avlon start at high ideal (1600 RPMs)

Cross posted to a.at.Camry .. sorry if that brothers.

Regardless out outside temperature 1996 Avlon start at high ideal (1600
RPMs) and stays that way for five to ten minutes. Some mentioned to me
that its a oxygen sensor ?. I cant find it if it is. I suspect that
its something to do with the Electronic ignition put I am only
guessing. I Hope someone can inform me accordingly.
Thanks.

I've had the same issue with a 98 Camry CE - curious to hear responses.

I have spoken to a electrical car service. They has there is no sensor
involved (say for monitoring temperature) and that it something wrong
within a the electronic that that sets the engine ideal.. Could me a
software/hardware problem. I would also would be most interested in
what you find out. I also think toyota has a web site where you can ask
them questions ?.

Cold start / high idle speed of 1600 rpm is the way it is supposed to be.
As coolant temperature starts to rise, the idle speed is supposed to drop.
ANYTHING that prolongs engine warm-up (i.e., very cold ambient temperature
or a thermostat that is not fully closed when cold) WILL result in the
elevated idle speed taking longer to drop down to normal idle speed.

But before you go tossing parts at things, do get the ECM codes read just to
be sure there is no other electronic emissions component failure present.

Thanks I will get an ECM reading done. I guess that I can get that done
at most repair/gas station, i.e I need not go to a dealer for the ECM codes.
I need to restate that happens went the outside temp is 80-90 or more. I
live in southern Virginia !!. To me 1600 RPMs seems pretty high and
not good for engine wear. I have looked in a Haynes repair manual for
Camry 1992-1996 they mention a temp sensor in the air filter...will
check if one is in the avlon. I found nothing in the manual that talks
a bout idle speed.
Cheers

Philp,
I forgot to say thanks for the information. I did visit a neighbor
who has a 1997 and as you said his started and idled at 1600 RPM in his
garage. Local Auto zone will allow one to use ECM ncode reader for
free. I have to admit I was surprised that parts stores carry ECM
checker but they are expensive if you only use it a few times over many
years.
