⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow the engine to cool before opening any components.

Symptoms

•Reduced engine power during acceleration
•Hesitation or stumbling when pressing the gas pedal
•Check engine light illuminated
•Increased engine RPM without corresponding vehicle speed increase
•Poor fuel economy
•Unusual engine noises during acceleration

Diagnostic Steps

1
Scan for error codes using an OBD-II scanner to identify any stored trouble codes.
2
Inspect the air filter for clogs or restrictions, as a dirty filter can affect airflow.
3
Check the throttle body for carbon buildup or malfunction.
4
Inspect the fuel system, including fuel pump pressure and injector functionality.
5
Test the mass airflow sensor (MAF) for accurate readings using a multimeter.
6
Examine the transmission fluid level and condition, as transmission issues may impact acceleration.
