2000, 4x4, 4.0L 6 cyl engine running very rough
its a 2000 4X4 with a 4.0L 6 cyl engine.
it running very rough at idle, rough when cold but when the engine is finally warmed up it runs even rougher, no power, shakes and shudders under a load.
i brought it to a mechanic and he checked wires, plugs, coil pack, compression test and vacumm test all passed.
I have also noticed when the truck is good and warmed up a sulfury smell comes out of the tail pipe.
could this be a catayltic converter problem? what i have missed in trouble shooting? would a ignition module be the problem?
getting ready to pull my hair out!!!

Minus reading data directly from it and making sure its operatin gwithin parameters.. the only 'real' way to check it withotu the handy dandy computer tools is to unscrew it and make sure it isnt looking nasty as all heck.. thats about the best assumption I can make fo rthat. if they are still stocker son yoru truck, or at least over a hundred thousand miles.. I would probably recommend changing them.
