I was leaving my doctors on February 21,2019 I walked out to parking lot to start and it made a noise that I didn't recognize so it finally started after 3 attempts so when I got going it had rough it was fine when I left the house with it but on my way the check engine light came on so I decided to stop and have it checked the scan showed 3 cylinders 4 /5/6 misfiring so I replaced the coils and spark plugs but what caused the problem was it that the timing chain had jumped time causing the cylinders to misfire and also loose power it died in traffic twice on my way home causing a serious accident. I was on a public street with lots of traffic.
