If I sit in my car and let it idle for a while at operating temperature, the RPMs drop to about 600 or so, and the car starts vibrating a lot. Is this normal, or am I idling too low?
If I am idling too low, is this something I can fix myself? Is there some way to adjust the cable connected to the throttle (is that even what I would do?)?
Am I idling too low?

Well, the car should not be shaking at 600 rpms. My car idles around 600 once it's warmed up, of course it's a V6... Thinking back I think my Accord had a similar idle problem that somehow resolved itself. I'm not sure what regulates the idle speed besides the throttle cable (which you should be able to easily adjust from under the hood). Call in the mecanicos

Re: Am I idling too low?
What car is it? For most of my cars, fuel maps are learned, so disconnecting the battery for a few minutes will force the ECU to start from scratch and relearn everything. That includes idle speed, fuel/air ratios, shifting patterns (for an auto), and the radio and clock. Plus more.Warner wrote:If I sit in my car and let it idle for a while at operating temperature, the RPMs drop to about 600 or so, and the car starts vibrating a lot.

I just changed the battery on the Taurus and had to relearn the shift points and idle. It learns pretty quickly, but while it was learning, it shifted a bit harshly and idled a little high. After about an hour of my slow-start driving, it had adjusted and was running nicely. Computers in cars do a lot more than we realize.

1.6l, if that helps.
I don't know the details for the Geo Prizm's idle tuning, but diconnecting the battery (if you're willing to lose radio stations and such) is a good start. However, I don't think it's something you should be overly converned about, unless the engine really lugs.
Adjusting the throttle cable could achieve what you want, but I don't know if that's the proper way to adjust it. The car is fairly new, at least from the 90's, so the idle should be adjustable by some other way.

my STi idles at 1,500 when its first started up, but after driving for about 5 minutes it is idling at around 500-600. It's not a big deal to me but it does make starting a little less forgiving.. but I have become super comfortable in this car so its no big deal..
