2003 Nissan Micra Manual

hello
my micra is not pulling in 2nd or 1st gear doesnt get up to 30 mph easily, is this because it is clogged up with the rubbish from the bottom of my petrol tank, as it gets driven on empty often?
is there a DIY fix for this?

You sure the clutch is not slipping? If not below can cause your problem:

Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)

Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires
