Fuel Injection Problems of Toyota FJ Cruiser

My vehicle has an issue with failing to quickly return to idle speed when I let off the throttle or shift gears. It does this consistently and repeatedly. The other day it almost caused a major accident during inclement weather. When I let off the throttle, the rpms will continue at a relatively high rpm or actually climb. Then abruptly the throttle will "stair step" down. In the situation where it became very dangerous. I am cruising along about 40-45 mph in a different area. I pop over a little rise and all I see are tail lights and cars spinning and sliding everywhere. I ease off the throttle and like usual, nothing happens immediately. Precious feet are chewed before the truck even begins to slow. Instead of slowing down gracefully, the rpm hang actually acts almost like a cruise control. As I just start to depress the brake to actually slow the vehicle, the ecu finally decides to chop the throttle. By chop I mean abruptly cut off fuel to the motor. At this point I am nothing but glare ice, going down hill on an off camber turn. So instead of a gradual reduction and smooth shift of weight, the chopped throttle allows the tail to now slide out to the right quite a bit. I donã‚??t dare touch the throttle to try and finesse it a bit since it doesn't listen to what I want to do. The non-linear throttle response put me in a situation that I almost didn't recover from. It was almost as though in the middle of the turn, I jammed on the rear parking brake to slide the rear around. This was the effect because I was going down hill and turning so the rear wheels were un-weighted and more likely to slide at this point. By slowly letting off the throttle I was trying to not induce any abrupt weight transfer to the front. I had the right idea, the ecu didn't! this was just plain incredibly dangerous how the ecu is programmed!.
