Hi,

I was wondering if anyone has gained any improvement by blocking off the cold fast idle valve, a separate valve from the IAC on 94' Accords? Currently my engine idles around 1500 rpms on cold starts and slowly works down to 800rpms as it warms. I'm thinking about plugging off to lower rpms on cold starts. One foreseeable scenario, is that the engine wouldn't reach open loop as fast and may negate the lower idle rpm fuel savings?

Also, my 94' is an OBD1 car, thus only one O2 sensor. So, would hollowing the cat bring gains in mileage?

Thanks in advance, Jig
