All you need to do is disconnect the vac hose where is meets the throttle intake housing (the one that goes from the EGR to the Carb) and plug it at the intake. Go for a ride and see if the problem still persists....(I'm assuming it it sluggish or almost choking when accelerating from a stop or going up a hill) If there's no problem any more, it is a faulty or stuck EGR and needs replacement.
