Jerking o r misfiring under acceleration usually comes from engine o r fuel delivery issues, often worsened by local conditions:

Ignition Coil Failure Very Common in Minis:
Mini Coopers are known for weak ignition coils. Heat and local fuel quality accelerate failures, causing jerks while accelerating.

Clogged o r Dirty Fuel Injectors:
Contaminated fuel from local stations blocks injectors, leading to uneven fuel delivery and misfires.

Carbon Deposits in the Engine:
Buildup restricts airflow and disrupts combustion, especially noticeable during acceleration.

Transmission Issues in older Minis:
Delayed gear shifts o r worn clutch packs in Aisin automatic gearboxes can cause jerks.

Bad Fuel o r Water in Petrol:
Poor-quality fuel can instantly cause rough acceleration and misfiring.

Faulty Sensors O2, MAF, MAP:
Incorrect readings confuse the engine ECU, causing unstable acceleration.

Result:
The car feels hesitant, vibrates, o r loses power when trying to speed up.
