In my '93 5 speed, it kinda "bogs down" when I try to accelerate under 2000 rpm. After that, it accelerates fine. The engine revs fine in neutral, at all rpms. Any clue? TIA.

 

Check your injectors. Was a tune-up done recently? If so, just start the car and start unplugging each injector one at a time. The one that does NOT cause the engine to run rough is the one that's bad. But that is assuming of course that your spark plugs are all functional.

 

On a VE it's easier to unplug the coils than the injectors

Sounds like the injectors bro... had the same problem occur tome on the high way... um... have you tried using some fuel injector cleaner? Better yet take a multi-meter to the injectors... that works to if you know where all the relays are... the Hane's book helps alittle in diagnosing the problem and showing the wire diagnostics... cuz I don't remember the ohms for them, but I'm sure you can find all that out. Don't buy new fuel injectors yet! At $115 each... try to find out what the prob is first... lol

My bad! I meant coils, i.e. funny looking harnesses on top of the plugs. I am too stressed...

 

My guess is injectors, and don't get the remans.
Bosch/Nissan updated the design on the injector to reduce the clogging on the new ones.
The remans can't have that done to them.
