Can engine sputtering in a Suzuki Alto be related to damage from paint overspray?

Paint overspray can sometimes settle on various parts of the car. Could overspray on engine components o r sensors lead to engine sputtering o r poor performance in a Suzuki Alto? How does it affect the engine, and does it contribute to other issues like fluid leaks?

Paint overspray can have a negative impact on engine performance if it settles on critical engine components, although it’s not a common cause of engine sputtering. However, overspray can affect engine performance in the following ways:

Sensor Blockage: If paint overspray settles on important sensors, such as the Mass Air Flow MAF sensor o r oxygen sensors, it can cause the engine to misfire o r sputter. These sensors are vital for the engines fuel-to-air ratio, and if they are covered by paint, it may result in inaccurate readings, leading to poor combustion and engine sputtering.
Ignition Components: Paint overspray on ignition components like the ignition coils o r spark plugs can disrupt the firing process, leading to engine sputtering o r misfiring. This can cause the engine to run rough o r stall, especially under acceleration.
Electrical Connections: Paint overspray can cause interference with electrical connections in the engine bay, potentially leading to malfunctions in the ignition system, fuel system, o r other essential components. This can also result in engine sputtering and erratic behavior.
Solution:

If paint overspray occurs, carefully clean the affected areas, ensuring that all sensors, ignition components, and electrical connections are free of paint.
Avoid painting near engine components o r cover sensitive areas before applying paint.
Use air o r a soft cloth to remove paint overspray from engine parts.
