When I first start mine, it will jump to around 2,000 RPMs for a sec(When cold) and then come back down to 800. It idles around 800 rpms. Winter time, it idles a little lower because of changing weather conditions. Redshark, it could be the temperature changes. Temperature and weather conditions have an effect on how a car runs. When its colder out, the car uses up more gas, noises occur that you may not here before with expansion/contraction of the parts. I guess your car has been a little "under the weather" lately with this and the clutch problem. AHAHAHAHAHAHAHAHAHAHAHAHA. Damn I'm funny. That was a good one! (Gives self a pat on the back) Not really. I hear no one laughing. Oh boy, I think I' ll shut up now. <img src=icon_smile_big.gif border=0 align=middle>

lol yeah I guess you can say that about my baby. <img src=icon_smile_dead.gif border=0 align=middle> I guess since I haven't had it for that long I'm getting used to it's changes and stuff for the first time. I'm so paranoid about it gee wiz... <img src=icon_smile_tongue.gif border=0 align=middle>
uhm, mine idles at about 1000 to 1200 rpm. Good or does this not matter? <img src=icon_smile_question.gif border=0 align=middle> I have also noticed when it's cold it idles at 2000 rpm, especially when i'm running late and don't let it warm up. When i hit the first stop sign the rpm stays around 2 grand.
I was gonna ask someone about this before. Sometimes, like when i stop, like pull into my driveway or something, after I put it in nuetral - it will rev up to like 2000 by itself. It's done this a couple times and it's really weird. What's goin on here?
my idle is all fuc*ed up, in the morning when I start the car it revs up to 2000 than down to 1000. when I'm driving in between gears it holds the rpm it's at instead of falling instanly, I hate it. have you noticed when your coming to a stop and you push the clutch in and your still rolling the idle holds at like 1500 than slowly drops. these cars have very weird idle patterns.<img src=icon_smile_tongue.gif border=0 align=middle>
The idle stays high when the car is still rolling. The ECU knows the car is still rolling and assumes you are going to grab another gear, so the ECU keeps the RPMS up untill you come to a complete stop. It is a "feature" of the car/ecu.
This is why when you disconnect the VSS (Vehicle Speed Sensor) wire from the ECU your car dies when you come to a stop. The ECU gets confused...
On some cars, aftermarket parts (CAI, BTB, etc) can make it worse...or better, depending on the ECU and the mods. Mine does the same thing.
NORMAL idle should be 800 RPM with the car not rolling, but you should always check the idle with the car fully warmed up. The ECU raises the idle when cold to warm the engine up, and to make sure the HLA's are full of oil before you start driving.
