So i bought a 92 hatchback. It has alot of stuff done to it and i got a great deal on it. To fill you all in leme list some things I know about.

Full Tokico Suspension, Camber Kit and everything
15" Brozen Rota wheels
b16 motor
lsd b16 tranny
underdrive pulley
intake
exhaust
brand new paint, and headlights
new control arms
short shift kit

and some other stuff i dont know about

Anyway, so the only problem i have had with it so far is the idle. The guy told me he put a p28 in it and it solved this problem, which doesnt make any sense bc it uses a p30 since its a b16. It surges when it idles, and jumps from 1k to 2k. I went ahead and bought a virigin ecu for a b16 and am hoping this will solve my problem. Does this sound like the ecu or somethign else? Possibly a vaccum leak or the air intake control valve? What do you guys think?? Im new to honda. Before i had a gti and a mustang gt, so this is all new to me. Thanks!
