Truck feels sluggish and like it's over revving before it shifts. But not a tranny issue, throttle body? Or mass airflow sensor?

* Check your air filter. A dirty air filter can restrict airflow to the engine, causing it to lose power.

* Check your fuel filter. A clogged fuel filter can restrict fuel flow to the engine, causing it to lose power.

* Check your spark plugs. Worn-out spark plugs can cause the engine to misfire, which can lead to a loss of power.

* Check your fuel injectors. Dirty or clogged fuel injectors can cause the engine to run poorly, which can lead to a loss of power.

* Check your exhaust system. A blocked or damaged exhaust system can restrict exhaust flow, causing the engine to lose power.

* Check your engine's compression. Low compression can cause the engine to lose power.

* Have your vehicle's computer scanned for codes. There may be a sensor or other component that is causing the engine to lose power.
