Hi, My car coughs, splutters, and stalls after fuelling to over half a tank. If i fill the car to less than half full I have no problems, but if i fill it to full I experience problems. This Problem seems to be getting progressively worse as I used to be able to fill it to at least 3/4 full and experience no problems. The problem seems to occur quite irregularly, sometimes immediately after fuelling & sometime 15mins latter. After driving around for a while and as the fuel level is reduced the vehicle begins to perform well again. Once while experiencing problems I removed the fuel cap and discovered a lot of gurgling noise coming from the tank. Fuel filter has been replaced. Fuel quality is good.
Thanks heaps

Hi Wilf77,

This seems to be a venting problem and is the Check Engine Light showing?

After removal of the fuel cap, does the performance of the engine improves, at least for a short period of time?
