I filled up my ej22 powered beetle and drove it for a few hundred miles one day last week. It was really hot, and after running for about an hour, it didn't want to idle. It actually stalled in traffic and took 30 seconds to restart, and it ran like hell. I stopped for lunch, and it was fine afterward.

 

Driving home, I was on the interstate for 40 minutes, going around 70 mph. After getting off of my exit and cruising into town, the car lost all power and would barely run. After a few seconds, it died completely. I coasted through a green light and into a gas station.

 

I thought I might have run out of fuel. The gas gauge isn't accurate, and I've never tried to calculate the mileage. The fuel pump sounded like it was running with no resistance, aka pushing no fuel. I opened the fuel cap and fwoosh!, it was under a big vacuum. The tank visually expanded. I hit the key and it fired right up.

 

I need to install a vented gas cap or something.

 

That is all.

Damn right you do...
