Thanks Katana...worth a try if the problem persists

Hi scythe, thanks for the information....I will talk to Lexus Chester to see if they can do the same. a tip from the American Lexus site was to try switching to "power mode", did this and the issue seems to have gone away at the moment but not sure if this is just coincidence??

Yeah you are right Steve...we will see how things develop in the coming weeks, will post results once known

Hi Steve, the floor mat was the first thing Lexus checked initially, the flyby wire throttle is one suspect, MAF sensor another suspect. The dealer says there is no fault code displayed on the diagnostic machine?? The search for a resolution goes on!!

Thanks Phil for the information, in the states there were a number software updates for the 460 so I am wondering if these have been done on the 460, I would be surprised if they had not. the car is back with the Lexus dealer who are again trying to solve the erratic throttle responses which seem to occurs several times a week but then can go a couple weeks without a problem??

Hi again Mark, yes I understand this but sadly my beloved 460 is residing with "Chester Lexus" who are again attempting to solve the problem. the 460 is with them for the week to enable their 460 technician to drive the car throughout the week to try and solve the mystery of the erratic throttle responses, but pictures will be posted when the car returns home.

Hi Phil, thanks for your prompt reply....just for clarification I was referring to the engine/transmission software set up in the Lexus rather than physical differences. Many states in the USA has different rules in respect of emissions which I presume are different to those in the UK/Europe, I could well be wrong in this respect but I am hoping my post will throw up some answers from 460 owners here in the UK.

I have a 2007 low mileage LS460 SE with a full Lexus service history, the car has covered 70k. the erratic throttle responses seem to come and go and the local Lexus dealer seems baffled by the problem, the Lexus owners club in America has pages of owners having the same problem but of course engine/transmission setup/software will be different in the USA so may not be relevant. have any members had issues like this with their LS460's and if so how were they overcome.

Thanks Mark, appreciated
