Ford Focus 1.8 Zetec Petrol - Ford Focus (2000 X reg) Running Lumpy - ARandall

Hi, My focus has started having a problem where it runs lumpy,the symptoms I have are:

Fuel Gauge is inaccurate and only moves between 1/4 and 1/2

When petrol tank is fuel the car feels like it's holding back above 5,000 RPM

When petrol is low the car won't gain any power when starting uphill and just limps, this also happens when driving normally and can be difficult to start.

Any ideas as to what the problem is would be appreciated.

Fuel pump comes to mind but don't throw cash at it have it tested first or codes read.

Fuel pump has been changed now which has solved the lumpiness. Sender unit is faulty though so no petrol gauge. Since this has been done though my car feels slower, almost like it's ever so slightly reluctant to go full whack through all the gears.

The spped is steady enugh I suppose but the revs don't feel as free as perhaps they could. Any ideas?
