Fuel related Power issue?
Hi there, I'm new to Passion Ford, and just bought a 2002 Focus ST170 about 2 weeks ago.
Absolutely loving the car, but have a weird issue, which I'm sure is probably something experienced before...
The car under heavy footed acceleration literally just cuts all power in certain gears and only when hitting certain RPM's, for example in 2nd at about 4000RPM etc - As soon as I fill up the petrol tank the problem goes away.
As I get just below half a tank of fuel left the issue starts occurring again.
Any advice would be appreciated, thanks.

I wonder if the fuel system needs an overhaul, it cannot hurt or be expensive to swap out the fuel pump but my first guess is that the breather is blocked and as the tank gets low it is causing a vacuum. Easiest way to test is run half a tank then remove the fuel filler and drive it like that, if the problem goes away then it is breather.
Also, get a cheap diagnostic port reader and plug in to the diag port and read off the fault codes, Google the codes and you will see all the common problems and fixes.

A quick google suggested maybe a fuel filter change and look,for a filter on the pump too

I would like to send the car in for a service in anycase, but do you think this will be an expensive thing to have fixed? D
Do you know of any good Ford specialists in or around Guildford / Farnborough areas?
