You used injectors you "had laying around"? Do you even know the flow rate of those injectors? It wouldn't surprise me if you're running the wrong flow rates, and leaning the hell out of the motor.

 

yes they are stock oem honda civic 240cc injectors

 

Well, 240 is the correct flow rate for the B20A/Z, but I would look into either picking up a new set of 4, or sending yours off for cleaning and testing, just to be sure. "Sounds like a subaru" isn't very descriptive, though.

 

Just a dumb idea I had from experience the other day, Try turning the car and while running pull the plug wire off a spark plug one at a time and see if the engine's idle changes at all. Do it to all four, I had one engine have two wires mixed around was causing it to misfire and bog. had a second engine have a bad spark plug that wouldn't ignite the fuel. both I discovered by isolating the cylinder with the above method.
