There is a lot of mention of immediate shut down, which I agree with, but it did not happen. Because it was not shutdown, we know that the flashing CEL did not stay illuminated. If there was an issue that was going to cause the engine to self destruct in seconds/minutes, would the light not have continued to flash? A misfire will cause a flashing CEL. The problem clearly seems intermittent. So the solution is to have a proper durametric read of DTC history and go from there. Or as an alternative he could continue to hang out here and be lectured about something he can not change...
