Hi everyone, I am new to the hondaswap fourms and Im wondering if you guys can help me out. I have 96 jdm B18C in a 98 civic ex/ek. Motor is stock and I have the basic bolt on right now. CAI, EM, CATBACK,NO CAT/TESTPIPE. also used the wiring harness from the stock d16y8 with some slight mods. Using JDM p72 ecm
My problem is my idle is random and seems to be higher the colder it gets
When i come to a complete stop it always drops bout 500 give or take.
Its Idling anywhere from 1500 to 2500 when going 20 in netrual
If car isfully warmed up the idle is normal when still but sill high when going 20 in netraul.
If car is fully warmed up the idle will somtimes surge very hard from 1500 to almost stalling and will stall sometimes(very annoying). This is normally going 20 in netrual.
Things ive done to try and fix this problem
Clean IACV
Timed to a T
Smoked intake for vac leaks(none)
New TPS(old one was bad)
Other Questions that could help me fix this problem
Do JDM b18c(1996) have a fast thermo valve?(cant seem to find mine) (looked under TB) (maybe not good enough)
Also had to wire the black box under intake(Forgot the name)(for butterfly intake)Im getting 12v from the sensor with key on/engine off. Is that correct?
Thanks for any input. please dont bash me if i didnt post this correctly for im am new to the froums.(first post ever for any fourm) also new to the honda world as this is my first swap. Again thanks for any input
