I bought an 04 TL just last week and for the most part it seems to be a great car. One odd thing is the way it starts though. It starts relatively quickly, but when it catches it seems like it catches kind of rough......not like your typical Honda. I read some threads on people having to crank the car multiple times because of the ULEV system, but this doesn't seem like the way this car is exactly. It also idles kind of rough after starting, but smoothes out. Any ideas?

car intentionally runs rough to aide in the precat heat up process. they acheive this by making the engine intentionally misfire.

 

^ Sounds like to me, mine never does that.
