B20b Idle problem
I've searched through and saw a couple things, but nothing that really helps me with my problem.. Im running a 90 Civic Hatch w/a B20 swap. When the car is idle , it revs 1-2 and back and forth forever and ever... I thought it was the IAC valve , and replaced it but that didnt fix it.. Im thinking a vaccum leak somewhere maybe near the intake manifold butnot sure.. Anyone have suggestions??

Where u located? If that's not the problem I just fixed my integra in less than an hour and didn't replace anything. Just hit me back up and i can take a look at it.
