I have a flashing check engine light & rough idle problem. I got the car used back In May. SES light came on, checked plugs. There was oil in the plugs so we did a valve cover gasket repair, along with new plugs & coils. Drove car 2000 miles to Florida, SES light came back on the day we got there. Drove car for a couple weeks, SES was flashing. Stopped driving the vehicle for two weeks, then had to drive it to work. SES light flashed twice on the way home, rough idling as well. Started my car the next day, drove around the block & light is continuously flashing. I'm getting the code read next week, I'm driving my brothers for the time being but I need my car fixed. Any ideas on what it could be? Thank you

When check engine light flashes if means you have a cylinder misfire so I would say find out which cylinder it is first when you get the codes and change that plug and coil again
