Car makes a tapping noise when car speeds up so does the tapping?
well to answer you original question, i would need to ask questions, number one; wheres does the noise seem to be coming from? number two; is it directly related to how much the throttle? answer, possibly from it being a front wheel drive car and it being the axel, if it is just speed related then it probly is something that is loose.
more likely to be tappet noise
first check oil level in engine
if oil level is coreect have a mechanic adjust tappets, and tune engie
if you are using lower rated octane fuel than engine is tuned for this will also give tappet noise in engine
