Default Defeating high idle.

Does anyone know if the crazy high idle on cold start is time sensitive or temp. sensitive.
Because if it is temp. sensitive putting a resistor into the sensor wire would trick the computer into thinking it was warm and reduce the idle.....assuming the resistance goes up as the temp. does, normally.
So who has figured this out and done it already?
This is so hard on the drivetrain when you engage drive with the idle up around 1500.

This is how ALL cars are designed to get them up to operating temp so they can run more efficiently. Unless you reprogram the software i the ECU which NO one has been able to do I don't see it happening.

You should let your car warm up first before you start driving. Unless you're on your way to the emergency room you can probably spare the extra minute.

Year of car? How many miles?

After first start I put it in gear about 2-3 seconds later to back it out of the garage, push garage door button and verify door closure, back out the rest of the way to street. Then off we go. 10-15 seconds elapsed time approximately.

A variety of possibilities and we'll need more basic info on your car. Tranny fluid maintenance done recently? Engine or tranny mounts replaced? Any other odd running issues occurring?
