i've still got this problem. <_< happens in mornings just after a cold night sometimes doesnt even have to be cold, all other features of the car are off apart from the stereo. <_< Not only that, but after about 15 minute (thats about 3-4 minute warm up to the minimum "temp guage" then a 10 minute drive when the car gets to ---> fully warmed, and you come to a stationary position either at the lights or anywhere the car shudders a little as if you've just done a huge stretch, ( a few km's) and the cars suppose you could say gets use to the rev and all of a sudden you stop and the computer doesnt know wat to do but stutters. Up to that point i realise it happens and jolt the gas, and give it a few revs to try and stablize the shudering. It slowly goes away after that point. Only happens rarely like 1zz-fe said. then again my car is a 2002 model <_< i doubt toyota would do anything to help me.
