Strange Idle Behavior.
When sitting at a red light the RPMs sometimes dip and the car starts to vibrate a little and then it goes back up.
other times the RPMs spike up past 1200 almost like someone is gently reving the engine.
dont bother suggesting i take it to the dealership, not an option right now

hmmm... sounds familiar. Was your ac on? I have similar symptom with the ac on. If it is I'm thinking it's related to ac compressor. Just dropped it off at the dealer yesterday for ac and other problems.
