I have the exact same problem all the way down to the black tail pipe, the dealer was no help. I did notice that it happens more with extreme cold or heated days...always on a cold start. After driving for at least 5mins and you turn off and on the car ... the light will then go off. When the light is on traction control doesn't work and I believe ABS doesn't work as well(no sure on the ABS as I haven't tested it, I know traction for sure).

My car is the 06 RWD GS300 as well.

Any help anyone can provide will greatly be appreciated.

This is a DEFINITE Carbon Buildup issue.

Ask/demand dealer to start a TAS case (Technical Assistance System) on your vehicle.

I strongly advise you to call Lexus Corporate---Lexus is aware of such carbon buildup issues.

BRAND NEW...Boxed...never mounted...will open box to take/post actual pics later.

im wondering if it is normal for the 06 GS300 to consume a quart or two in between 5000miles oil changes??

is it normal to add oil in between 5k miles oil changes to add oil to keep the level above minimum??

im fairly new to this car..

My 06 GS300 would stutter around 5000rpms when i floor it when idling, it would stutter (pause) at this point for about 2-3secs, then climb up to redline; after i repeat the same procedure 2nd-3rd time, it would just go to redline without pausing, or stuttering....It would do this "cycle" everytime after initial Start. Any thoughts??? I recently brought my car for service due to CEL which was diagnosed to have a bad Gas Cap (replaced), and a leak in the evap system, i dont think this stuttering is related to an evap. leak though.

Car runs smooth, no noticeable power loss/miss fire when driving, No CEL currently , Stuttering happens with either a cold or warm engine.
