I have question. What should be the idle speed in neutral on the tc? When I first start up the engine it takes a few minutes to idle down, but after it does the idle bounces between 600 to 800 rpm's. Is this normal? My tc only has 500 miles on it and it runs smooth, accept for when you are at a complete stop.

It should not hunt idle, it should be steady. It is not possible to set it, it is controlled by the ECM. If yours is not steady, there is a problem to address. Take it in for service, this is not something for the home mechanic and you don't want to change anything related to engine control under warranty unless you are willing to forego warranty coverage for your power train.

thanks. I will be taking it in for service.

Remember though, if you turn the steering wheel when the car is idling, it will bounce up the rpms due to engaging some force to assist you turning the wheel.

And the a/c will cause the idle to change as it goes on and off. Were you running the a/c???

i've had my car's rpms sort of "bob" up and down when i put the clutch in and am still rolling. as soon as i stop moving it settles to where it's supposed to be. it only happens rarely though. do i need to have it investigated? closest dealer is an hour away. thanks

When I got in the car at lunch, the idle was at 2K. First time I had ever had that happen. After driving it a bit, it idle returned to normal.

^^^That's crazy! 2k definitely seems out of the ordinary. I have yet to notice anything like that with my idling.

 

[lo bux racer]

I saw the same thing once. It was a fluke, or it's some weird thing the programmed into it to happen only once in a long while.

Maybe it was cold. Mine idled around 1500-2k in the dead of winter.

Yeah in Kansas Winter during that ice storm geez mine was about there for a minute or two cause it was freakin cold!
