I have a 2000 Lexus GS300, when Im driving the car for a while and come to a complete stop (redlight) it looses take off power, i have to put the pedal to the medal just for the car to go, it takes a while just for it to get to 20MPH, I took the car to my mechanic and he said that, i might need a new throttle body or that its loosing conection with the computer, im wondering if any one is having this same problem with their car, or if somone knows how to fix.
