I have a1997 acura cl 3.0 it showedme the check engine light it says my system too lean and fuel trim malfunction i have already changed the fuel filter the fuel pump and the main fuel pump relay .... and it still looses power when im driving i dontknow what else it could be kkk

 

clean the MAF(Mass Airflow Sensor) sensor. could also be a vacume line leak, or bad 02 sensor. if not the obvious check plugs, wires, and distrubitor cap.
