Hello there i am new to the forums. I have a 99 vw beetle 2.0 with a manual transmission. Lately when i put gas into the car it seems to fight me to start; hesitating, chuging,etc. This only occurs when you open up the gas tank and push the metal flap down. Im guessing that flap may he sticking or if there is a sensor in there it maybe causing this issue. Any ideas?
