High Idle

Does anyone think it is odd that when i start my 4cly from cold in the morning it shoots up to almost 2K rpm. this seems a bit high.
I know that more than 80% of the wear on a car engine is due to cold start up and would think this would increase wear.
Maybe it gets the oil flowing quicker or something.

Is there a way to reprogram the idle to a lower RPM at start up.
I noticed that as it warms up the idle drop almost proportionally. Is there a mod for the electronic choke
and if so how could on tune it down or disable it ??

If you were to do something like disabling your electric choke, your car would run like crap, if even run. Its the same thing as starting your weed-eater without a choke. Its there for a purpose, and its normal. Its purpose is to get the car to the normal operating temperature as fast as possible, oil pressure also has a little to do with it.

 

It is part of your emissions. Until the engine and exhaust heats up enough for your oxygen sensor to detect it and go into "closed loop" operation, the high idle is needed.

I wouldn't screw with it personally.

 

It's normal. At least I hope so... my truck does it.
