b16 low rpm motor problem??

ok i put a b16 in my 90 da and it was great worked good for a month and now at low rpm anything under 4 if i hold the gas at a serten place for a few seconds it will act like it is loading up and if i give it a little more gas it will go away does anyone know what might be causeing this?
thanks

ok i forgot to add that i only have been getting around 200 out of a tank of 91 so i know there is something going on with my fuel system?

lack of torque + heavy car.

Sounds like poor ignition, did you do a tune up yet?

yeah i have new cap rotor plugs wires before i even started the motor up and it ran great and now it is doing this tomorrow i am going to check the ecu to see if it is throwing any codes i am wondering if it could be an o2 sencer??

could be 02…but I always say that.

check the wires,plugs, fuel filter, ETC.
