One of three things is occuring -- in order of what I would check:
Exhuast restriction - check for a catalytic converter that may be clogged.
Fuel pressure is too low - a pressure test is in order.
Too much air is getting into the engine - make sure all hoses are attached and are not damaged in any way.

Good luck!
Plugs could be shot.
