i think this is the right place to post this as i think it may be some sort of wiring issue. a friend of mine has an 88 civic hatch with a B16a motor swapped in. the motor and harness is out of a j-spec 1990 integra and the coil and plug wires are all in good shape the issue is that when vtec is supposed to kick in around 5000-5500 rpm sometimes the engine kicks hard and the tack goes nuts then there is power loss. the engine never really dies, it just seems like it wants too. this doesnt happen all the time only sometimes randomly. sometimes it runs niceley. nowhere in town seems to be an expert on these motors and was wondering what you all think. sorry if there is a thread on this somewhere i am new to the forums and unfimiliar with it.
