Hello all!
I wasn't sure where the best place to introduce myself was and as I am (actually the wife is) a new owner of a GS430, this seemed to be the best place to start.
So, quick notes about me. We live in Phoenix Arizona (hence the screen name) and I am a full time graphic designer who is always looking for freelance work as well, and have been in the field for right at 10 years. My wife just graduated with her RN license and is looking for her first employment as she has been an LPN for about 4 years now.
My current vehicle is an '04 Chrysler 300M Special (the last model before the box on wheels design). My wife had an old '98 Sebring which we recently sold.
So, how did we end up with a Lexus? Well, my father just upgraded and picked up a new '07 LS460 and sold his old '01 GS430 to my wife. It is black with light tan interior and as far as I know, loaded. Has the Mark Levinson audio system, heated seats, spoiler, 17" wheels, moonroof. The only thing I know it does not have is the navigation system.
Just over 111,000 miles on it and in great condition all around. However, the car just took a little cross country trip from Ohio to Arizona as my wife picked up the car followed my parents out who own a vacation home here. She noticed something that did not feel quite right. Now myself, I have no experience with any foreign vehicles, not to mention of this luxury class.
The vehicle has always been serviced at the local dealership and so I feel that may be expected of me to continue to do so. However, it is still a combustion engine automobile, so I can't imagine it would be extremely difficult to change my oil or even replace the plugs and wires. This is where joining this board comes in and educating myself all I can about this model.
So my first two questions if I may, on my first post are:
1) Is the process complicated to changes simple routine maintenance items on the GS430 like fluids or plugs and wires? Is this a vehicle that should always only be serviced at a Lexus dealership?
2) This is about the issue my wife noticed on the drive out and that I was able to experience tonight as I got to drive the vehicle for the first time. The car seems to shift normally, with shift points around 10-12mph into 2nd, 20-25 into 3rd, and 40-45 into 4th. They are quick and smooth. However, when you go to hammer the pedal down (such as to accelerate onto a highway or quickly merge over into passing traffic), the car goes into almost a stall mode or as if it choking. It will not downshift until you let off the pedal and you must slowly give the throttle gas.
When she first told me about it, I thought possible transmission slipping, but there is none of that. Next thought was bad gas, but since she drove over 2,00 miles and filled it up with premium, that was taken out of the equation. My thoughts then moved to plugged or dirty plugs and/or wires. I am not sure if/when the last time they were changed.
Another thought is electronic transmission shift points programmed in the computer. I believe the vehicle just recently had (again though, not 100% on this) a transmission fluid and filter change. I am not sure if this vehicle has a feature like this? On my 300M Special, when I recently had the fluid and filter changed I was getting very hard downshifting point from 2-1 and I had to take it back to the dealer to be re-programmed because of the new fluid and slightly different level. Not sure if this kind of thing would affect the downshifting when you are looking to accelerate out of the gate.
I appreciate any thoughts an input you might have. I will be sure to be reading over these boards to learn as much as I can about things.
Thanks!

Welcome to CL, be sure to check out the Southwest forum, there are lots of helpful Lexus guys out here and they even have fairly regular meets, no doubt they could help you with your questions. For a good local alternative to the stealerships try Motortek in Mesa (Main & Dobson), great guys with fair prices.

Thanks for the tips.
@csq860 - I will keep that shop in mind, only about 8-10 miles from me (I am in East Mesa).
I think I've got a few beginner points to start with on the hesitation issue from doing some small reading here. Going to run some Techron through it and see if I notice any difference or has any immediate effect.
Once I find out for sure how old (or new) the plugs and wires are that may be my next stop. I'm even tempted to run some SeaFoam through it as that would clear out pretty much all the carbon deposits.
On a secondary note, thanks for the quick replies. I joined another Lexus board last night and posted and after nearly 40 views, never received one reply. I'm glad to see I will be able to communicate with a much greater ease here!

Congrats and welcome!!

Kyoei USA in Tempe is also good with excellent prices.
As far as the car hesitating when you mash the pedal, try resetting your ECU. You will also want to clean your MAF sensor. These are common symptoms, usually because the DBW doesn't help in this regard. Do a search and you will find all the info you need. Good luck!
And as csq mentioned, check and follow up with the SW section for upcoming meets and events. Hope to you see out sometime.

Excellent, I will probably start with the reset of the ECU as well as clean the MAF sensor (which by the way, found a great picture tutorial here MAF sensor removal/cleaning tutorial GS430 if it hasn't already been linked elsewhere).
I will also run a can of Techron through it once we burn through this tank of fuel. Hopefully one of these three small simple things will remedy the situation.
Thanks again for the quick replies!

on a 2001, I think you change the plugs at 80K mile intervals. So if it's been done once, you're good for a while.
I suggest you take it for a spin yourself and see if you can reproduce the problem
