I've had my 300 GTi for almost a year, and I'm getting close to 7,000 miles now. I'm having a problem with the engine after fill-ups. After filling up, the engine starts ok, and idles ok: But when I give it some throttle, it dies. This started happening at around 3K miles, but not everytime I fillup. Sometimes, I fillup about an inch below the top, and I still have this problem. It doesnt happen everytime I fillup, but it is happening more and more frequently. Recently, it happens about every other fillup.
When I'm having this problem with the engine dieing, I have to be patient, and apply throttle slowly. After restarting 3 or 4 times, it will usually go.
Has anyone else had this problem? Is it a maintenance problem?
