i'm installing a 99 gsr into my 94 civic si hatchback and have a skunk2 intake manifold. the 99 doesn't come with the EVAP purge control solenoid valve and the skunk2 manifold has the little nipple for it. what do i do, can i just cover it up, if i do that, what would i do with the line coming from the canister. do i have to find a obd1 EVAP purge control solenoid valve and install it. need help asap as i'm gonna drop in my motor. thanks.
