The car is shaking!
Hello everyone
I have LS430 2006 with 120000 Miles.
Recently, I got this shaking while the car doesn't move problem with VSC off and Check engine warnings.
I Tried:
-Changing Timing Belt
-Changing Gas Filter(Petrol Filter)
-Changing Plugs
-Changing Coils
-Cleaning Injectors
And still, the car shakes when I'm in traffic jam or waiting someone even if it is on D, R or N shift.
I spent nearly 3000$ on this problem and still not solved.
Any ideas?
Thanks in advance

Sounds to me like the next step would be to check the engine mounts. Ive seen em go on a few LS here but not many. Have you tried simply viewing the engine for movement while idling? There should be very limited vibration.

Properly running LS430 engine is smooth as silk - absolutely no vibration, at idle you should barely be able to tell the motor is even running. Like other have said check clean or replace MAF , make sure TB is clean. Bad MAF can produce rough idle so I'd check that first and it takes 5 minutes or less to swap in a new one to test, if not then check mounts.

I checked the engine mount and it was fine.
I'll check the MAF sensor and throttle body.
The problem is that the vibration is not permanent, it comes for 1-2 minutes and when it finishes the RPM drops down and the movement of the car at low speed becomes irregular. Another thing, when the high vibration comes, if I'm in P or N and press the gas paddle and leave it, the vibration stops.
Thank you all for help, I'll check what you told me.

yup, mounts... how did you 'check' them? they are hidden and only thing you can 'check' is outer metal shells... the mounts are hydraulic! if all oil leaks - it will look ok but make car vibrate.

each engine mount is about 100usd (x2) and rear tranny mount (x1) is like 50 bucks.
slightly tricky to replace the engine ones, mechanic should be pretty good to do it in an hour or so....
when you are able to compare the old one, just taken off a car, and new one (to install) you will be able to see (most probably), what 'world of difference' really means...

So, I replaced the engine mounts... Same Problem.
Replaced the whole engine (Used .. cost 760$)... Same problem.. so I returned my old one.
Replaced the exhaust(Don't know which part)... Problem Solved .. until now.(Used ... cost 400$).
Thanks guys for your help ... I hope the problem will not come again
