Hi
Today was a nice day to take a drive.
Whilst driving through a forest road I had the window down and could here the engine noise echoing off the trees and could hear the engine quite clearly. However, every time i blipped the throttle i could here a slight pinking noise. Only a couple of pinks every throttle blip.
When i put my foot down more I could hear the pinks a bit more but not too noisey.
Does anyone know the cause of this? and how can i fix this please?
many thanks

Either the ignition timing is out, which is unlikely or there is a build up of carbon on the top of the pistons, and/or around the valves.
Normally a decoke would sort this out, which means removal of the cylinder head, unless you can find something to put in the fuel to clean it out.

Mine does the same (84,000 miles on clock).
My garage said nothing to worry about. I did try BP ultimate for a while and it seemed to help.
As Johnboy1 says just a small build up of carbon deposits in head.

hi i have not used this forum for a long time but im now looking to buy a black mk2 gs300 sport gain so id thought id pop in here, ive seen this post so decided to reply.
i had an x reg black gs300 mk2 sport i bought it when it was 2.5 years old with 32k on the clock and i remeber driving in the summer with windows down and every time i hit the throttle id get a pinkin noise as well, my car was under warranty so i handed it to lexus who reset the ecu and the problem continued, at least 3 attempts were made to resolve the pinking but it continued, i was told this pinkin noise exists on all gs300 models and there is nothing anyone can do about it, lexus even said if they fitted a brand new ecu it would not solve the problem, i dont think this post is much help to you but the i was told the pinking issue could not be resolved.
