My car started jerking out of nowhere and then it would sound like a race car after it jerked. When coming to a complete stop and then pushing down on the accelerated and would not accelerate as it usually would and would need to be pushed down more in order to get it moving. Put more fluid in, changed spark plugs, and put this liquid in my gas tank and it helped for a while but then happened again.
