Started having hesitation with my acceleration when I would press on the pedal with my 1999 GS300 about a month ago. It would drive fine for a while but at times I would have to press the pedal all the way down just to move at a decent speed. My pop works at Ford and connected a computer and received codes for the throttle position sensor. Mind you he is not a Lexus specialist so he assumed that we had to replace that sensor. We did that this past weekend but I still have the same problem. All we did was replace the sensor. Do you guys think I need a new throttle control motor as well or need to calibrate the sensor with a Lexus hand-held tester?

take it to Lexus and they will fix it for free. There is a class action lawsuit for this very issue and they are fixing these issues at their cost. I missed the boat and replaced several components that failed sporadically.
Wow did a little research and I see that Toyota and Lexus are recalling vehicles for acceleration problems but it doesn't pin point my exact problem and the years of the models being recalled are in upper 2000 and mine is a 1999. I appreciate the heads up. Definitely going to look into this more. If anybody received this same problem and went to Lexus and got it fixed free of charge, let me know how it went. Thank you.
Thank you Burny. After knowing and reading that I realized I was sent something from Lexus in the mail 6 months ago regarding this problem but did not have it at the time. I have a 99' gs300 with 175k and I went into Lexus and brought them what I received in the mail and the print out from the Toyota settlement and my Throttle Lever Assembly was fixed free of charge ($700 job).
