1994 Honda Accord Q&A
1994 Honda Accord Question: What is causing rattling noise coming from underneath car when I press on gas?
There ma be a loose heat shield or a broken hanger. When the exhaust is cool try banging on it in different spots with the palm of your hand. - Chevy Power
I agree with chevy power but it could also be a catalytic converter - goodguy
def in exh system somewhere seek est from muffler shop - globalhelper
Check converter heat shields , they rot out and get loose. Your description of symptom fits that perfectly and is quite common. - ziptie12
