Electrical problem
2002 Other Mini Models 4 cyl Front Wheel Drive Manual 60000 miles

i have had the car diagnostic tested and nothing has come up. Its an intermitant fault, it maily happens on a cold start and is worse in winter. Also the exhaust which is less that a year old had a rasping noise coming from it.

Do you
have the same 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
