I was just parked on a pretty steep hill facing down and started the ignition. But to my dissapointment the engine started with a pretty big shake and started to tremble unusually with the TCS light on about 30 seconds longer than usual. I want to see what was up with the car but someone was waiting for the space and block traffic so I moved. After a few blocks it was ok I guess, but I really don't like this feeling. I think I experienced this once before. I just got a oil change 2 days ago and my car has almost 20,000 mi. Anybody have the same experience? Or comments? Thanks!
