Gs300yute

Hello everyone, I have a 1998 Gs300 that has an issue and I can't find an answer, I'm hoping that I'm in the right place. When I drive my car and come to a complete stop it sometime shuts off, most of the times it would either vibrate like it's struggling to go, it would rev but wouldn't make the car go any faster. I recently replaced my throttle body thinking that's what the issue was, because I had a similar issue 3 years ago and that did the trick, but this time, nothing has changed, the car's still skips even when I'm stepping on the brake, it sometimes jump or leaps, it's kinda kinky. Would any one happen to know what this problem might be???

Welcome to CL. We do have specific forums for questions like this.

But, in general, the first question is: ........do you have the Check-Engine light or any codes lit up?

May be Pedal NOT Throttle "Pedal positon sensor" its almost a $500 part. toyota supra takes the same part. My GS would shut off outta nowhere.....Step on the gas pedal and nothing happens...I got no codes!
