I have a 2000 GTS manual, and today I noticed that when I started it, it started to rev itself about five times from 1500 RPM to 2000 RPM. Then it stopped and went down to normal idle just under 1000 RPM. Is this normal?

Oh, and I tried restarting it numerous times in different gears, with the clutch held in, and then released, and the same thing happened. I'm thinking that since it's like 40 degrees outside and that the engine was cold, that it does this in order to warm it up a little. But that's this my theory. And I just noticed this today for the first time when it finally got cold outside.

Anyone else have this issue, or is it normal? Thanks.

Its the choke thing. Remember in the old cars when you had to pull out a pin when it was cold to start the car?

Now its just built in the computer grin

Great, I thought so but I just wanted to make sure. Never had a car that did that before, it's kinda cool when I think about it. Thanks for all of the help guys! thumbsup

dont wanna scare anyone, but it could be somthin else. Although it probly is the cold weather, and i havent experienced that yet, it may be the map sensor. I dont know anything too much about cars or that part in particular,I think it senses exactly how much gas needs to be combusted and it regulates it or sumthin, pukebut in my 90 celica GT, it cost 300 bucks for the part! AND 300 MORE to install it! just wanted to run it by you guys, let me know if it could be that, i dunno, but i hope it stays as being the cold weather, and not this other $600 problem.

The Celica uses a MAF sensor, not MAP. MAP is generally used on factory boosted cars. The MAF detects how much air is going into the engine by using a hot wire that is calibrated to stay at a certain temperature. The more air is flowing past it, the cooler it gets causing the ECU to send more voltage to compensate. The difference in voltages is the ECU input for airflow. You paid 300 dollars to install a sensor?? eek Hope you used KY for that rofl To the original poster, you might wanna check your MAF for debris and/or oil buildup... If there's none, it's probably the weather like others said...
