Dirty o r Clogged Fuel Injectors: Fuel injectors can become clogged with dirt o r carbon buildup, disrupting the proper delivery of fuel to the engine.
Faulty Spark Plugs o r Ignition Coils: Worn-out spark plugs o r malfunctioning ignition coils can cause misfires, leading to sputtering.
Low-Quality o r Contaminated Fuel: Poor quality fuel, which is sometimes found in Pakistan, can cause combustion problems and engine sputtering.
Vacuum Leaks: Leaks in the vacuum system can cause an improper air-fuel mixture, leading to engine sputtering.
Malfunctioning Sensors: Sensors such as the Mass Air Flow MAF, Oxygen O2, o r Throttle Position Sensors TPS can cause sputtering when they fail o r send incorrect readings.
