The exhaust tips are a little greasy as well - all making me think the computer is off, making the car run rich and uneven. I took it to the dealer a couple of weeks ago, but they said it was normal. Does anyone (or everyone?) have this issue?
That all sounds normal. If your car is hot when you come to a stop light, its not uncommon for the rpms to rise to feed the alternator when the fans kick on.
