Hesitation when hitting throttle....
Notice some slight hesitation when "hitting it" as I'm laying into it more to decide on drop, exhaust, etc. and testing car's true set-up. Read a post where spark plug change eliminates this. Is this common and did plugs stop it?
Only run 93+octane....

I suspect that the hesitation you are referring to probably has to do with the throttle-by-wire system and / or the automatic transmission. Unless you have something wrong with your car, spark plugs won't change it.
I have no idea what "more to decide on drop, exhaust, etc. and testing car's true set-up." has to do with this thread.

Car is not in snow mode
Does that make sense?

Hesitation - intermittent but maddening!
I too am experiencing hesitation on accelleration. I've taken my 2007 to the dealer, which naturally found no problem after keeping it 2 days but only driving it 8 miles. I only use premium fuel from Cheveron - no cheap gas. The frequency of the problem is increasing. Also, my mileage has decreased by more than 10%. Grrrr...

I'm fairly certain what I am experiencing in not normal. First of all, it is only intermittent. Sometimes, accelleration is smooth. Other times, I can take my foot off the brake, step on the gas and it's as if I'm not even touching the gas pedal at all. I can depress the accelerator at least half way down and I coast and then suddenly the power kicks in. People are honking at me because it's as if I am coasting through intersections.
I've had the vehicle for 11 months. This began happening about 2 months ago.
If this is normal, then this is my last Lexus.

Definitely not like a trans problem (been there, done that with other vehicles.) The car was new, with about 3 miles on it when I took delivery.
I will try to find a regional manager for Lexus service and see where that gets me.
It's pretty frustrating when my mother's 10-year-old, 4 cyl. Camry has more power sometimes.
