Look I had a similar failure with my Nissan Quest 96, when I reached a semaphor or a stop down the revolutions and how it wanted to turn off and the engine was shot, then it accelerated again as it cost him a little work but he leveled and advanced as if nothing had happened, they told me that the spark plugs would be etc. But it turned out that the spark plug cables would be changed and composed one hundred, I hope my experience helps you, luck.
