Mazda MX-3 Acceleration problems by year

Car is wanting to stall every time I come to a stoop. Must put in neutral to keep from doing. Mechanic claimed it was throttle body carbon build up but that did not fix problem. Seems like this might be a common problem with this vehicle. I would like to know how this has been fixed in past and not let mechanic keep guessing.*Ak

I have taken the car in for several check ups and inquired about the idle problem. Was told that there was nothing that could be done about it. I would just have to get use to it. Car idle will drop so low that the whole car will shudder and then the idle will pick pack up. This will continue as long as sitting still at a intersection or traffic light. Once car is in motion there is no idle problem.

Brakes are failing and the car accelerates at the same time. Please describe details. Tt
