Why does my Suzuki Bolan engine sputter while accelerating o r climbing hills?

Whenever I try to accelerate o r go uphill, my Bolan starts to jerk o r sputter, like it’s not getting enough power. It happens more when the van is fully loaded o r has CNG installed. Could this be a fuel delivery issue o r something else like spark plugs o r timing?

Sputtering during acceleration o r when driving uphill is usually caused by a lack of fuel, poor combustion, o r weak ignition. In the Suzuki Bolan, especially when running on CNG o r under heavy load, common causes include:

Weak fuel pump for petrol o r low gas pressure for CNG

Worn-out spark plugs o r ignition coil

Incorrect ignition timing

Clogged air filter, restricting airflow

Faulty distributor cap o r plug wires, especially in older models

When under load like climbing o r accelerating, the engine needs more fuel and spark. If anything in the fuel o r ignition system is weak o r dirty, it will cause sputtering o r jerking. Get a mechanic to check fuel pressure, timing, and spark quality, and clean o r replace spark plugs if needed.
