Slow acceleration from stop..Video
Gs430 2008...when I push hard, it has slow acceleration, the strange thing is, it has faster acceleration when I push less than hard. when I push hard at like 20 or less, it has a bad response, but after 40 it goes well. the first acceleration I pushed almost all..it was bad response..and the second acceleration was better because I pushed maybe quarter of half in the beginning. weird thing... thoughts! I turned the VSC off so to not think the VSC holds the car or something.
first acceleration the acceleration starts from 40 s
second acceleration
first acceleration the acceleration starts from 40 s

my 06 would spin the tires from a dead stop with 19 staggered f-sports and v12s.
Have you tried disconnecting the battery for like 5-10 minutes? It'll reset the ECU/all your programs etc.

Spark plugs, remove and clean your throttle body front and back of it, clean your maf sensor, put a new air filter, run a combustion cleaner seafoam or any other good cleaner through the intake manifold.

Spark plugs took only 20,000 km. Cleaned the throttle and maf sensor and I put new air filter recently. Did not understand the last thing about cleaner seafoam..however I think spark plugs and air filter and so on effect in all speed but I only have a problem in the bigening

Did you just start having this issue or are you just noticing it. Seems like what you are describing is normal with electronic throttle system. Drive by wire is designed mainly for emission purposes, this is why it restricts you from full throttle but yet you can ease into it. There are devices out there that connect between the throttle pedal that trick the ecu so you can get a better throttle response ( eg. sprint booster ).
If you feel this is due to mechanical issues, i would check maintenance items as ibidu1 suggested.

In all combustion engines carbon build up happens most engines produce it more then others. If theres carbon in the engine, it can choke the engine and for the engine to compensate the drop in idle it raises the idle. There are products called seafoam, BG, and many others. It is always best to have a good computer to data log exactly what is going on with all the sensors.
What you do is with a hot engine, you pour the solution into a cup and get a small strip of vacuum line that will fit on that capped off vacuum plug on the intake manifold. With the engine running you let the vacuum from the vacuum line suck the solution until you finish half the bottle, shut off the car and let it sit for 30 min to allow the solution to soften up the carbon. Then repeat the same step and this should help clean the internals somewhat. Dealerships call this a top engine clean, or combustion chamber cleaning.

its sound in the first video like it is choked or !something..could it be the catalytic converter
Try the method that I mentioned to you. If you dont have seafoam in your area you can probably go to the dodge dealer and order 2 bottles of mopar combustion chamber cleaner. With a hot engine, spray it through a blocked vacuum plug on the top intake manifold.
