    Is it the Z22SE or Z22YH engine you have (guessing it's the Z22SE), could be the EGR valve sticking, maybe worth removing and giving it a thorough clean out and/or remove it, fit a blanking plate and get yourself onto the Z22SE site and purchase the cheater from vocky who builds them, charges a tenner for it, have to say mine was abit like yours and ended up doing this mod' along with airbox mod' and shorter VXR intake pipe and car is so much better all round, also changed air filter (standard Vx one) fuel filter and plugs, while I was at it.
    Cheers Pete
