Get a scan tool or load the OBD Fusion App with Lexus PID pack and watch the engine parameter KCLV, which is the engine knock correction. If in the low teens, your engine needs cleaning. If north of 20 to 25, do nothing as it's fine as is.
Just a FWI: piston/combustion chamber carbon build up creates potential for detonation. Detonation pulls back ignition timing that reduces performance and fuel economy.
^^ A lot like running cheap 87 octane fuel. lol
So, get some before and after data. If the engine hits >23 kclv, then its most likely fine. That said, it needs a clean MAF, Fresh plugs, good oil, clean air filter and all that jazz...
Let us know if you have question.

Interested in knowing if perhaps a member has used or experience with the following product;
BG Aerosol Carbon Eliminator Spray - 12 oz.(PF06-N1A5) (with Aero cone?). I've used CRC GDI IVD Intake Valve & Turbo Cleaner and wonder if similar / more effective etc. Also used BG EPR flush.

I used this kit and am happy with the results so far:

Wasn't aware of the STP setup, thanks Protholl. Appears similar to the Berryman Intake Valve & Combustion Chamber Cleaner # 2611

I've had no experience with the Berryman version or the BG one so I can't say which would be better. Good luck!

I bought one of these and use on all my cars doing the running engine drip cleaning. The one I got was open box for $49. Works great. This is the method the Dealer service uses. I do my cars periodically to clean and also keep clean so not to build up.
You can also get this and do it a cheaper way.
Make sure you change the oil and filer after you do the cleaning process.

The key thing everyone needs to keep in mind is that carbon took hundreds of hours to accumulate. Most chemicals can't undo this in a tank of gas or an hour idling.
3 and 4GR owners need a maintenance plan if there vehicle primarily does short trips!
