Decreased fuel efficiency
Engine stalling during acceleration
Rough idling
Unusual fuel odor
Increased emissions from the exhaust

Diagnostic Steps

Scan for error codes using an OBD-II scanner to identify possible faults.
Check fuel pressure to ensure the fuel pump is functioning correctly.
Inspect the air filter for clogs or restrictions.
Assess the condition of the spark plugs and ignition system.
