On several occassions now, I have experienced a sudden loss in power when cornering slightly faster than one usually would in city driving. Once the car is straightened out, the power comes back on as if nothing had happened. This only seems to happen when my fuel tank shows about 1/3rd left (or less) in the tank. My suspicion is that it's got something to do with the fuel not being delivered to the engine effectively through the pipes as the fuel gets shoved to one side of the tank. Has anyone else had this problem and is there anything that can be done about it ? As for my problem with re-fuelling the car.....I find that after driving for at least 10km or more in a moderately spirited manner, removing the fuel cap at the gas station usually leads to a lot of hot gas being emitted, often with a fair bit of 'bubbling' via the flap at the top of the fuel tank. For the next 5 whole minutes, it is almost impossible to feed any fuel into the tank as the kickback pressure constantly leads to the fuel pump being stopped. As a result of this, I have now been reduced to driving my car when it's cold straight to the nearby petrol station to have it filled up. Question : is this normal and if so, should I avoid pumping fuel into the tank when the temperatures are running high ? (I live in Singapore where it's HOT all year round). If it's not normal, what's the solution ? This really becomes a problem when I take a drive up on the highway into Malaysia and I need to re-fuel the car somewhere along the way. I find myself having to wait a LONG time till the car has cooled down before attempting to re-fuel.
