RANGER WITH 4.0 V6 STUMBLES OR MISFIRES ON ACCELERATION[ INTERMITANTLY. HAVE 62K ON THE CLOCK.

2001 Ford Edge • 62,000 miles

It stumbles or surges intermitanly on acceleration. Have a rotten egg smell from exaust. Is the cat cooked? Also what could've cooked it at this low miles. It is leaking oil from passenger side valve cover. It drips onto the pre cat and burns off. Never anything on the ground. No CEL.
