Clicking noise

Have 2006 explorer hearing a clicking noise, like a playing card in spokes, gets louder upon acceleration. Started happening after went thru some puddles. Could something be loose.

Maybe exhaust related. Exhaust manifold crack or gasket. Or maybe further down by the catalytic converter

It is now stalling unless you keep foot on gas.
