I'm looking for a bit of advise on my MY13 Evora. So I started a trip from Wisconsin to Tennessee with no engine issues. Along the way, I had to fill up at stations that had up to 10% ethanol fuel. I was a bit bummed about that, but anyway. So 727 miles later, I reach Tennessee and shut the car off for the day.
The next morning I start the car up and it was so rough I didn't think it would stay running. After about ten seconds of extremely rough idle it sounded like it got to running on all cylinders, but became rough again with any application of throttle. After about a minute, it ran perfectly fine. No dash warning lights came on. I figured it was maybe the ethanol as well as the altitude change and it wouldn't do that again.
Unfortunately, every time I start the car up for the first time in the day, it starts fairly rough. I had to drive back to Wisconsin at the end of the week and after the initial rough idle that day, I had no issues.
So since the trip, I've ran down the gas tank and filled with 100% gasoline. I still haven't gotten any warning lights, but struggle with the initial rough idle. It has never been as rough as the day after the first 727 mile journey, but that first start up of the day isn't fantastic. Is this a TADTS and I've simply broken the car in or is this something I should take the dealer to have this looked at? Suggestions?
