I need a list of the EGR/Trouble codes for a 1994 Ford SHO Taurus

When you say smell like exhaust, does it smell like rotten eggs (sulfur)? If so, could be catalytic converter clogged up.

Well your rotten egg smell and your run issue is usually caused by a plugged-bad cat.convertor.

Sounds to me like the catalytic converter is shot. The "rotten egg" smell and stalling out is a dead giveaway. The converter is plugged up and cannot let the exhaust out of the tail pipe like it should. The exhaust is building up back pressure in the exhaust system, causing the engine to lose power and stall. Take it to a qualified shop and have the catalytic converter replaced.

run fault codes as the lack of rotten eggs smell is an indication that the cat converter is not functioning.

EGR (exhaust gas recirculation) valve may be stopped up with carbons. This would account for some loss of power as well as odor if leaking around intake. If I remember correctly, egr tube originates just above catalytic converter on this model. Condition may be early signs of cat failure ( commonly accompanied by "rotten egg" odor). I recommend having emission system checked by certified tech to avoid uneccessary component replacement.

sounds like your wires are switched around. have replaced the plugs lately

Code 33 is EGR opening not detected, this is caused by a plugged EGR exhaust passage in the upper intake manifold, this is a common SHO engine fault, the valve works but the engine does nothing that the computer can sense, since no gas flows, to verify this is the problem open the egr at idle, the engine should almost die, if nothing happens or only a tiny change in idle speed or quality the passages are plugged, if it does stall or get real rough the egr position sensor (usual code for sensor is 32) may be faulty or the valve is sticking. I was a ford dealer tech for 30 years and did quite a few of these, there is a TSB (technical service bulletin) about this problem

It could be the oxygen sensors but when you said there is a bad odor I would bet that you have a bad EGR valve. It will send a code for the oxygen sensor if there is problems with the EGR valve. A lot of the time the smell is like rotten eggs when you have a bad EGR.

Sounds like you may have a vacuum line off or ruptured going to the EGR valve. The burning smell is probably the catalytic converter. When the engine runs rich you will get a sulfur smell that smells sort of like rotten eggs.

your egr valve is sticking
