pinging or ticking/clicking?

If its the latter, thats normal. These cars tend to have noisy injectors. I bet 25% of the guys here have that "problem".

This has been asked probably 15-20 times before...next time search and you will find what you are looking for. i.e. search ticking or pinging or clicking

Check your knock sensor. I had the same issue, I replaced the sensor and the issue was gone. The car got more responsive throttle and faster. I use 89 octane with no knocking.

More info on this knock sensor?

My tick is pretty loud.

89 octane??????? but i thought lexus 1ls must use premium 92 or higher, at least thats what the gas gauge said, and the gas filler cover
