Ok my friend has a h22a1 in his civic hatch with a fluidyne and a flexalite fan but the bleader valve in just barly hitting the fan blades by like a 1/4 on a inch should I just cut out the 1/4 inch on the blades and see how that works?..................................One more brain teaser.....My car only at idle revs from 600 rpms to 1600 rpms and runs fine after that......it's only at idle.....I have changed the IAC valve, the oxygen sensor, the PCV valve, and I reset the ecu, and it's not a vaccume leak. the only thing I think it could be is the fast idle valve. did anyone else have this problem? And do you know what it could be?
