Ive tried this twice now and its getting on my last nerve. I have a 98 civic dx hatch D16Y7 5spd. Im trying to swap a D16Y8 Auto mani. I also got the d16 hondata intake mani gasket. which work fine with the y7 mani. My y8 mani came off a 98 auto ex. I reused my y7 injectors, rail, tb,ecu, purge solenoid. Im using the 98 ex throttle body gasket. Plugged the small orifice on the back of the mani that wouldve been used for cruise control. And plugged one big one on the front. All vaccum apperas to be good, i used new clamp on everything. Should i be using the y8 purge solenoid?? Some people say yes and some say no. I know the sensors are on right cuz i marked them with tape. I ran the pcv straight to vaccum and tee'd the line and sent it to the purge solenoid which then goes to the charcoal canister i think its called. Also the manifold i bought is ported for a gsr tb which is funny cuz i can use one seeing that the IACV is in my y7 tb... Im sure lots of people have had these problems. After searching im posting this becouse i cant find the answer alone. Any suggestions??
