Just a quick update on the problem guys. I poured in more petrol and the noise at the start hissing from from the tank is gone, and the car drives fine now. I have also successfully bought extended warreny for my car today. $895 for 40,000kms, or two years. I will wait a week or two, and wait till my petrol tank gets to around 1/4, and it starts to stutter, and jerk with the power delivery again, and then take it to honda for them to check it out for free under warrenty. I will let you guys know what THE HELL IT IS...

Thanks for all ur support through this........
