Rafferty95PF

So not sure how to describe what is happening. I have a 95 pathfinder and lately it has been having trouble accelerating. The issue started while trying to back up, it is running but moves like a slug then going forward it continues to move sluggish but clears up if I shift to neutral, rev the engine, and shift back. Today it actually died while in drive but at a stop. I was thinking either egr valve or tcc solenoid. I checked the tranny for fluid and smell both were fine. Any thoughts?
