Bouncy fuel and tach gauges
I was wondering if any of you guys have any problems with the tach and fuel gauges kind of bouncing around. The fuel gauge only bounces when you turn the key from off to on but settles to it's proper level quickly. The tach needle bounces somewhat when making a shift under hard acceleration. This happens on my LS430 and others that I have test drove as well. Any fixes? Thanks all!

04+ or older?

My 01 does the same thing. It really doesn't bother me that much since the fuel gauge only bounces on start up and I don't really look at the tach while I am flooring it. But it would be interesting to hear what others have to say

Must be a 01-03 thing. Doesn't happen with the 04-06 clusters.

I wish it was an 01 - 03 thing. My '04 UL has a bouncy fuel gauge on start up. I had the fuel pump replaced when it failed a few months ago. Didn't change the gauge behavior unfortunately. The tach and other gauges are normal and never bounce.
I have a worry that it's the cluster. Anyone solved this?

It seems like you answered your own question.
Under HARD acceleration, my 01 has a slight "bounce" on the tach, but im assuming its from gunning it. As I slow down, the tach "bounces" a bit as well when it shifts to the higher gears to cruise. My gas bounces only at startup.

Mine is an 04 and does this as well. Only at startup.
I think it's the fuel tank sending unit, Denso Part # 9550104:

Toyota dealer quoted me 1 hour of labor to replace. Just not 100% sure if this is actually the problem.

I'm going to go ahead and get the fuel tank sending unit replaced. My dealer is 100% sure that is the issue as he tested the cluster and everything is normal. I'll keep everyone posted.

PS. The link that mentioned the fuel gauge modules as the problem was dated 2004 while I received my info in the year 2010. Possibly the service manager had a number of complaints over the additional 6 years of the LS430 being in service to come to his conclusion. Personally, I can not confirm a definitive fix.

Well turns out the fuel tank sending unit didn't fix it, and the dealer is blaming the cluster now.
If anyone can confirm a fix, that would be great. As others mentioned ,my fuel gauge works fine, but the bounce is annoying
