Default 98-00 LS400 Traction control problems

Hi all,

I have owned my 99 for almost a year now and have recently done the timing belt, water pump, valve cover gaskets and replaced most of the front end parts and upgraded the wheels to 18" ls430. I just got it out of the shop having the front end aligned. Since the new wheels have been on the car I have been having problems with the traction control light flashing (more times than not it causes it to not want to accelerate) when accelerating from a stop. I didn't notice the problem with the factory 16's, but I have done a lot to the car since I drove with those wheels, so I am not sure... I have searched and have not found much on this issue. any advice as to where to start?? thanks in advance for the support!

Arick

what size are the tires front and rear?

My guess would be drastically mis-sized tires (should be same overall diameter all around) or damaged ABS sensors.

Hey Puredrifter-
Thanks for the reply..
I'm running (matching set)245-45-18's all around. I thought about the abs sensors, is there a way to check them? Also- will a faulty front abs sensor cause this sort of problem or would it only be caused by one on the rear of the car??

Thanks!
