“My issue: one morning I started my car to leave for work. When idling it felt a little rough but stopped after just a minute or two. The next day it also was rough but escalated to a shaking and the check engine & the service engine soon light both came on. I took it to a european auto mechanic to have it checked out. Their code reader said there were two cylinders misfiring. What they told me is there is no way at 52k miles there are bad injectors, it must be the gas station I had used. They recommended I run a take of gas from a chevron or shell and all should be good. That is what I did. …”
