A Toyota truck may lose power due to several factors, including a clogged fuel filter, a failing fuel pump, or issues with the ignition system such as worn spark plugs or ignition coils. Additionally, problems with the air intake system, like a dirty air filter, can restrict airflow and reduce engine performance. Engine diagnostic trouble codes can help identify more specific issues that may be causing the power loss. Regular maintenance can help prevent these problems.
