If you live in a state that doesn't open the hood during inspection, make sure your catalytic converter is in good shape (or new) and you should pass no problem.
NJ is fairly close to CA, CT and MA in emissions testing, and my 93 crewcab goes right through with just a cat. All the other stuff is physically mounted there, but does absolutely nothing but take space and add weight at this point.

well I don't think it is the lack of emmission control system that is causeing the prob bob blocking off the egr inlet and bypassing the air pump should only make your check engin light come on unless you put in a chip so i would check the ignition system 1st then worry about the smog crap latter it don't help ya or hurt ya it is there mearly to reburn what the cat won't I've seen a cracked insulator on a plug make a 5.0 run like poo poo think small start small don't waste time and money on thing that you know might or might not fix the problem pull your plugs i bet a dollar to a donut that you have a fouled or wet plug or some typy of ignition problem
