Lecky

Finally after months and months of trying different approaches to cure my Lexus 460s hesitations and sudden lack of power (limp mode style) have found the reasons why (in my case ) a collapsed tension pulley.. the cars knock sensor was picking up the intermittent vibrations my broken pulley was making and thus regarding the timing.. end result engine sounds and feels smoother and feels like all the 380 bhp are alive and kicking like they should be.. very happy with Lexus of Bolton UK for eventually finding the culprit..

Hi again.. well your recommendation BG44K injector cleaner has made a huge difference and I've only done 40 plus miles since adding 2 tins to my full tank of Shell V power fuel.. like you said add one tin per 8-10 k miles and that should do the trick.. thanks for posting your findings bud.. like you I was going to sell my lexus now it's a deffinate keeper.. I just hope more 460 owners experiencing the same problems come across this post.. 

Many thanks

Stu.. 

Very happy to hear that your lexus is still performing like it should do.. with a bit of luck I'll get my two tins of that injector cleaner tomorrow.. did you use one or two tins per tank full of fuel ? 

Thanks for replying.. 

Hi there.. stu here from the UK.. how's your 460 still doing after you added the injector cleaner? I have the same year of car and mine has started do the same annoying hesitation issue ... Been into my lexus dealer and had them test drive it .. " yep something is a miss here" they told me.. one ECU reset later and I drove home.. that's done the trick or so I thought.. it's now  less than 70 miles later and  the hesitation limp mode feel again is back... big sigh.. so after some research I came across your post and thought I would join the lexus club and reply to you and see how your cars still going nearly a year on?.. I have ordered two of those additive cleaners so hopefully like you I can make my 460 good again.. please give us all an update if you don't mind.. cheers bud..

Hi all,

I believe I have posted here before a long time ago with my old LS430 LEX, I now have a 2007 LS460L with 110K on it now. I have owned it for a few years now, since 65K miles, and recently I started having acceleration/hesitation problems. I did alot of research, and didn't find very many good answers. I did have the transmission and engine ECU update flashed, with some improvement, but after that didn't solve the problem, I was convinced it was the cylinder head replacement deal, which was way out of my budget with 5 kids....and I thought it was ridiculous that a flagship sedan would need that kind of serious motor work with just 100K on it. Anyway, my mechanic suggested BG 44K fuel system cleaner, NOT available at places like autozone. He sells it for $28 per can, but I found on Ebay for $16.75 and up with free ship. First and foremost, I ALWAYS used quality, premium gas (Shell V-Power or QT), and Techron additive from time to time, so I was super unconvinced about his recommendation. I had even listed my LS for sale, again, convinced that the motor had cylinder issues after reading blogs about LS460 acceleration issues. Also, for the record, I have NO affiliation with BG or anything like that. THIS STUFF WORKS! It truly fixed my hesitation problems, completely. I am no longer selling the car, and am happy again, as it accelerates like it is supposed to. Feel free to read many other peoples reviews on this stuff, its amazing and really seems to work. After i drove it to wrok (25 miles one way) I thought i felt a difference, by the drive home, I KNEW I felt the difference, after the full tank, i was truly smiling. I have ordered 4 more cans for my other vehicles and boat, and suggested it to my friend with a ISF, my brother with an SC430, and my buddy with a Vette. I guess these LS460 cars are just picky after a while and maybe the injectors get gummed up? I don't pretend to be a mechanic, again this was suggested by my Lexus mechanic, After alot of depressing research with no real answer, just wanted to share my experience with any other LS460 owners, as it is a beautiful car, and I was disappointed in what I was thinking the problems I had. It was the best $17 I have recently spent, and if you are having similar weak/lack of acceleration or hesitation issues, i would say TRY IT for less than $20. I believe you can go to BG's site and find a local dealer, again, not autozone or O'Reilly or anything like that, says professional use only lol. Also, need a funnel, comes in a coke can basically. Just my 2 cents, hoping to help out any other LS460 owners out there depressed about their car, it seems most people just said they'd trade it in and buy a new one, but I'm not that rich 🙂
