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 :)
Very glad to hear I was able to help someone else out, and glad it worked well for you. Some people say the difference is "just in your head" but you and I can feel it in the pedal, so I know it works. Glad I could help again, take care :)
