After the car is warm and driven, the RPM's seem to fluctuate a little when I am in drive and stopped. I can sense a tiny bit of vibration too, it does not happen all the time but when it does, it worries me. The rpms for example will go from 750 to 900 and then jump around a bit. I know if I take this to a dealer, it will be hard to reproduce since it does it once in a blue moon and chances are that it wont happen when im there. Any one know about this or experienced similar?

FYI, car has 32k miles and it had the cold start TSB done at 15k.

theres a cold start TSB for our cars?! hmm, i always said my car had too much trouble starting when its cold outside. if someone can send a link to that TSB i would appreciate it..

and to answer to the OP's problem, i would just wait it out until it gets worse or happens more often. the dealer won't do anything unless the problem is reproduced unfortunately..

rpm fluctuation happens at idle SOMETIMES ~75-100rpm if im at a stop and i turn the steering a little, but other times it ok, yet ~100rpm at idle is no big deal though i guess it depends on the load on the car at the temp.

I've noticed it as well. Been happening since 15k miles.. I've got 17k now. Just idling at a light and there will be a faint shudder/drop in RPM giving that feeling it's about to die. Very slight, but yeah, I have noticed it.

as i said it fluctuates but does not seem like its dieing tome, its hardly 100rpm

I am going to go to the dealer next week and let them look at it but im sure they will come up with "We cant reproduce..etc". I will just tell them to update the ECU, I am not sure if I do have the latest. Its the vibration that is annoying me, I hate any kinds of vibration and especially at a light or stop sign....its not normal.
