I recently purchased a 99 gs400 in mint condition. I had my mechanic check it and was also going to bring it to the nearest lexus dealer. The traction seemed to be working fine. One day, after it had rained I accelarated a bit hard and the traction engaged as it should have, but when I came to a complete stop, released the brake pedal and gently pressed the accelarator the traction went on and I was barely pressing the gas. I could actually here the noise coming from the engne bay as lexus says I should hear. This happened a few times over and over again so I shut the car off for about half an hour. There were no service lights that went on exept the traction light that went after afew blinks. When I restarted it, the roads were still wet, the problem was not there until I once again pushed the car and activated the traction, as the wheels were actually spinning. Then the car would do the same thng when I would come to a full stop. Eventually it stops doing it but only for a little while. I'm a newbei and would appreciate any help or just a few comments on what you pros think.
