i have heard all the idle problems, and i cant really seem to find mine. it normally starts after drivin for a minute or so, but when i come to a stop, the idle will drop a little, then surge up, then drop real low, and almost stall, but it will catch itself and live, and while its doin this, the car will jerk me when im stopping, kinda like im braking, then letting off the brakes, and applying the brakes again, what could cause this? i have a 55mm tb on with new tps, and iac motor, so i doubt its either of them? i have heard that a bad torque converter could be the cause, could that be it? or could it be a vacuum leak? im not exactly sure how to do a vacuum leak tho.
