gs430, noticing rough idle?
First off, I searched for the past 2 hours and have not been satisfied with any of the posts.
Today, was the first time I started noticing the rough idle thing that seems to be the problem with the GS400's. I am getting the exact same symptom. AC on, no rough idle. In the morning before it completely warmed up everything was fine. When I got off the highway and stopped at the light, i noticed the roughness kick in.
So right away, i drop by the strauss and pick up some TB cleaner and a toothbrush. At work there are a bunch of tools so I took them and removed the TB pipe sprayed the cleaner, and toothbrushed it. Damn that was a hard job especially since you cannot open the TB externally, and that thing was hot from the drive. Reasembled everything, and the problem is still there.
My question: wasn't this supposed to be a problem for the gs400 people? Or can this be related to my car having 84k miles and nearing the 90k service?
None of the other posts have ever found a legitimate solution to this. So can someone suggest something. Thanks in advance.

Even though you have the wire, I would not do this yourself. The connections should be soldered (4Ga wire to end terminals), it is difficult to solder 4 ga, it wicks heat away too quickly.
Check out www.teckkits.com - Paul Kwan.
His kits are excellent for about 75-80 bucks. Wasn't worth the time and effort for me to cut and solder etc.

ok update. So i just ordered the grounding kit. I got the black one with siver terminals. Will see what it does for the car.
Soo, nobody thinks this is a nearly 90k issue that I am having?
Oh, and I am doing Engine Oil, Trans Oil, Oil Filter, Denso spark plugs, and hopefully the grounding kit this weekend. I already did the K&N drop in two weeks ago.

When you talk about idel does it mean your RPM jumps around a bit? Because my car the rpm stays solid but you can feel the car bump like the engine is moving at idel? Do I have the same issue I thought it may be because of my Intake & Exhust?

No, i mean that the idle goes too low, and I get a vibration. It is a very common problem with the GS400. You can search for "low idle" and get a ton of info about the gs4s, and how most of them just tighten the throttle cable. I cannot even do that, since the 430 don't have a cable at all.
