Fuel System Issues: Problems with the fuel system can cause rough idling and stalling. Check the fuel filter, fuel pump, and fuel pressure regulator for potential clogs or failures.
Ignition System Problems: A faulty ignition system can lead to misfires and backfiring. Inspect the spark plugs, ignition coils, ignition module, and spark plug wires.
Air Intake System: A clogged air filter or issues with the Mass Air Flow (MAF) sensor can affect the air-fuel mixture, causing rough running and stalling.
Vacuum Leaks: Check for vacuum leaks in hoses and connections, as these can lead to rough idling and performance issues.
Throttle Body and Idle Air Control (IAC) Valve: Dirty or malfunctioning throttle body or IAC valve can disrupt the engine's idle control.
Exhaust System: A restricted or damaged exhaust system may cause backfiring and poor engine performance.
Engine Sensors: Malfunctioning engine sensors, such as the oxygen sensor or crankshaft position sensor, can lead to various engine issues.
Electrical Issues: Check for loose or corroded electrical connections that might affect the engine's operation.
