I have been having the same problem. Along with this, it feels like the ABS brakes are activating when I begin to move from a stop. Did you expereince this? I see your post was from a year ago, so wondering if you did find a solution that you can share.
Hi. I'm curious to see if you ever found out the problem or solution to your ABS activating when accelerating from a stop? I've been having a similar problem for quite a while now with my 2001 Lexus RX300, and no shop, including the dealership, has been able to figure it out. From a stop, I get an intermittent shudder before the gas engages, and the traction control light comes on for a moment. No other lights, etc... Thanks for your time!
