Car runs fine until I really get on it ,then hit the brakes.Then it wont idle and tries to die.Sounds almost like its missing or something.After awhile it starts to run good again.If it does die it is a bitch to start again.I've cleaned the IAC,checked the TPS,fuel pressure is good. Any other ideas guys. Thanks Stewart

That could happen with a low fuel level, fuel pump that is loose on its mounting, loose wiring harness that flexes from the inertia, or a serious vacuum booster problem.

thanks. The fuel level is usally1/2 or better. How would i determine if it's a vacuum booster proplem and how do i check the booster. Thanks again
