3rd & 4th Generation (1992–1996 & 1997–2001)Toyota Camry Discussion for years: 1992-1996 & 1997-2001
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
You probably need to narrow down what you mean by "cold". Lots of folks here from places where they consider a low of 40 F to be cause for multiple coats and long undies.
Its sounds normal... My car will go as high as 2200 RPM.
In Toronto when we get -15 C my car will start at 1200 RPM and slowly goes up to 2200 and then as its get warmed up it will drop below 1000.
On thing to keep an eye on is the time it takes for the temp gauge to start moving up. I find that 3 mins will be more than enough to warm up the car and start driving. At around 3 mins you will see the temp gauge move 1/4 of the way up.

That's really wasting fuel and making the car take longer to reach normal operating temperature. Start the car, fasten your seatbelt and then drive away, driving conservatively for the first few minutes. The time it takes to fasten your seatbelt gives the oil a chance to circulate throughout the engine. If it's below 0 F (not C) I would give the car about 30-60 seconds to let everything circulate.

That's how I drive my cars....just get in and go. Of course a really cold day here would 5 to 10 degrees F and I might let it run for 15 seconds before moving it..

theres several other important reasons besides oil circulation to consider when heating moving hunks of metal from below freezing to several hundred degrees under load.
anyways, a ballpark 4 cylinder will use less than 1/4 gallon per hour idling. roughly 1/240th of a gallon per minute or roughly an eighth of a cents worth of fuel(at $3 per gal.)
For whatever reason, if I just jump in and start the car it will usually start at 2200, drop to around 1600 and drop further as it warms.
If I turn the key on and wait a few seconds, it might only start as high as 1800 and drop normally from there.
Maybe turning the key "on" for a few seconds gives the oxygen sensor heaters time to bring them up to operational temperature, so they ECU can use them to trim the F/A mix?
I'm mostly blowing smoke out of my *ss, 'tho -- I'm seen conflicting info on exactly when the O2 sensors start being used for F/A mix trimming. It's gotta be fairly early, 'tho, otherwise why bother to have heaters on the sensors?
I took note of how it acts with immediately starting it when i insert the key and then another day waiting about 10 seconds with the key on prior to starting.
I'll try waiting 30 or 40 seconds see if the RPMs drop further.
Thanks,
Jay in MA

I gather 55 degrees doesn't qualify as cold? Or has my car just become a wimpy floridian car? My car starts up to 2000 rpms then drops to 1600 rpms. If I drive to the store and start it up for the way back, it goes normal at 1000 to 800 rpms however...
Interesting...1600 sounds a bit high to me. I currently live in San Diego, mornings are around 50, but it settles at 1200rpm at initial. Could it have anything to do with the lack of humidity here?

Eh, during the winter up here in Montreal,I usually run around 2000 rpm idle on a cold day. Nothing unusual... other than the fact that when I was running a straight pipe, it was hella loud. don't worry too much about it

Should I worry about it if its still doing it on an 80 degree day?
