Is poor acceleration in my Suzuki Mehran caused by faulty spark plug wires?

My car struggles to accelerate smoothly, and there’s a slight jerking feeling at low speeds. Someone said the spark plug wires might be old o r leaking current. How do I check this myself, and should I replace them all o r just the faulty one?

Yes, damaged o r old spark plug wires can cause weak acceleration, jerks, o r engine hesitation. In Mehran, if the wires are cracked, loose, o r leaking current especially in rain o r humidity, the spark wont reach the engine properly. You can check this at night by spraying a little water and looking for small sparks current leaks. It’s usually best to replace all the wires together if one is faulty, since others are likely weak too.
