I know the subject sounds funny, but that's a sound my '05 has started making when it's cold (when the car is cold, not the weather, it's about 100 around here these days!)...
I'll start up the car and it'll do its usual angry/rough idle viper thing and occasionally it will go FFFFFTT then idle a few more seconds and FFFFFTT again.. I wish I could have recorded the noise, but unfortunately, it stopped doing it the last two times I tried to record it.
It stops doing it once driving, even when idling at a set of lights.
It's a weird sound and almost sounds like a backfire after the FFFFTT.
Any ideas? Fuel injector occasionally stuck open? Exhaust leak?
