Hi, Please help me. A few weeks ago I started noticing a very different sound on the engine of my car. It had a rough rattling sound every time I accelerated and had a slight shake when it was not in motion- just in idle. I stopped using it for the past two weeks but last week I drove it once for less than 15Km and then it just started shaking and it was a really terrible shake I had to stop and let it cool off I bit. I then stopped for a few minutes and turned the engine off. After a few minutes I started it and then boom! Engine light went on and my car had no power. Since then I haven't touched it. My research says it might be a faulty spark plug or an ECR problem. Please advise if you can assist... Many thanks
