Did some research and found out the brake master cylinder, throttle position sensor and throttle position actuator were the problems.

levels that' hurts like the devil. My car will literally stop in the middle of cruising and won't pick up any speed unless I have my foot pedal all the way down to the floor, which also often times causes it to turn off on highways, all types of streets and other areas. Also with these items gone bad my car shifts so hard to the point where it jumps whenever I shift into any position. All in all the vehicle, I feel , is too dangerous to drive at this time
