Strange wobble at high speed
Hello all!
I have a 2006 GS300 awd with 116,000 highway miles, no accidents. The car has been well maintained and I have been keeping up with any issues. I have two right now that are baffling me a bit:
1. The primary one - I do a lot of highway driving, and when I am over 65mph, If I let off the gas (no braking, just off the gas) the whole car seems to wobble quite bad. As soon as I push the accelerator even a slight bit, the wobble completely goes away. This does not happen at lower speeds at all. The bearings all seem to be nice and tight.
2. I get an intermittent metallic "rattle" from the front drivers side when going over little bumps and potholes - sounds like a heat shield or wrench klunking around by the control arms, but only happens over little bumps, will Not happen when going over a regular speed bump or something of that size. I will also get a tenuous clicking noise from the drivers side front end when turning to the right into my parking spot. I pulled off the front drivers side wheel and firmly pushed and pulled and tried to bang on every piece in the well and underneath, and I could not locate anything with any sort of play/movement.
Please let me know if I can provide any more specific detail to help this out! I am willing to put in the money to get it right, but I don't want to go buying all new parts without at least doing some research first.
Thanks so much - Matt

I also noticed that metallic noise happens mostly at low speed as I pull into a parking spot, and i can almost get it to replicate over and over if i tap/pulse the brake on and off. this doesnt explain the rattling over small bumps, but does give me something!
Last thing - threw a P0430 CEL, bank 2 catalyst efficiency below threshold, anyone know common causes? o2 sensor? which one?
Thank you all so much again,
Matt

I have the same issue, kicks in a little faster though so its not as much of an issue. 75-80mph it starts by 90 it is scary - but when I'm on the gas I can barely feel it. Really kicks in when I let off.
Let me know what you find out. I'm replacing a couple wheels that look like they have some damage.
