knocking sound when push the gas pedal on 2002 Isuzu Axiom
Its hard to comment without hearing the noise first hand. It could be "back firing" due to a lean condition or misfire, it could be a noise created by a mechanical problem, or it could be a noise due to the engine moving due to a bad engine or exhaust issue. Get it check out particularly if you have a Check Engine light on.
