scottykilmer.com has a great vid on how to locate vacuum leaks. also, make sure your gas cap is tight.

Thanks, it doesn't have a gas cap actually but doesn't look like it's supposed to. I read that some models do not have gas caps but not sure as I just received this car and haven't had much time to look into it


Then how do you put fuel into the car?
