Hesitation, surging and crap mpg.

[Torque]

Been having problems with stuttering on acceleration, eventually came to conclusion it was crap petrol, it started after I filled up from a particular petrol station.

I've also got similar issue: [size=78%]http://foc-u.co.uk/index.php/topic,10534[/size]


I think I've checked everything I could and I think that my issue could be fuel related.
I've replaced the fuel, it did not help, however I think it could be because my tank have drain pipe blocked (only breather pipe is connected to hose).


Now waiting for Isopropylene to add some to get the water from inside of the tank.
