Engine Idle Funny

[deezeejoey]

My car seems to idle funny but only under certain conditions.

After my engine is already warm. I start the car is starts to jump up and down about a 100RPM. and if I put the car into gear without hit the gas the car jumps with the motor.

If I drive for a little bit it doesn't seem to do it anymore.

Why is it doing this?

It doesn't seem to do this when I start the engine cold (because it idles at like 1300 RPM until the engine warms up)


Edit:
My car is due for an oil change right now. (only have gone 3,020 since my last oil change.)

Bump, any ideas?

clean the TB inside, plate on both sides and clean IAC hole with a toothbrush. use good cleaner like sea foam deep creep.

does the car tell you jokes when it idles? LOL
jks

anyway, yea cleaning your TB/IAC would be the best idea for now...but judging from your symptoms it's not that bad.
