why do you want to bypass it?
bypassing it would actually give you a fluctuating idle, in most cases, probably worse than what you have now. bypassing it is mostly for racecars because they need colder air. you need ambient air.

When you say your idle is fluctuating, when is it fluctuating? At initial start up when the car is cold or after the car has warmed up? And is it a constant up and down revving, or is the idle sitting at one rpm at one time and then another rpm another time?Comment

Have you looked into other symptoms of a fluctuating idle such as air in the coolant?My Members' Ride Thread - It's a marathon build, not a sprint. But keep me honest on the update frequency!Comment

My IACV,FITV,Air boost are all bypassed no fluctuation problems. But if the IACV is bad (Can check the plunger with a 12v source) then it will still fluctuate. The only other way i know of is to have it eliminated through a tuneable ecu.
Also air in the coolant system will cause fluctuation issues, so try bleeding the system.Last edited by SOHC-FTW; 10-23-2012, 08:37 PM.

Quickest way would be a business card/thick card stock inbetween it and the plenum. It can be remotely located aswell as long as it's hooked up to the harness and w/ a block plate on the plenum, coolant isn't necessary either. Bump up the idle abit to compensate for extra loads like heat, a/c and lights.Comment

It's reving up from 1000 to about 1500 and going up and down. But sometimes it does it and sometimes it does really bad. If I let it warm up it doesn't do It. But when I get off the highway it's does it about 5 or 6 times and the idels around 1000. I've try cleaning bothe the aicv and fiacv and the I tried turning the top of the fiacv and cleaning it. Should I just replace them? Or try bleeding it?Comment

Why are you repeating yourself and asking for someone to repeat what they just suggested to you? Why don't you just go try it?My Members' Ride Thread - It's a marathon build, not a sprint. But keep me honest on the update frequency!Comment

I recommend searching the diy section for key words = idle fix. Search in "titles only" to narrow it down, you'll find what you need.
If after the above you still have an erratic idle, replace your FITV with OEM ONLY from www.hondapartsdeals.com. After this, adjust your base timing and base idle (search for the threads). If you have any issues after all of the above come back to us with questions.My Member's Ride Thread

had a cb7 come in and it had bouncing idle which sucks because i can't check ignition timing and it just needed to be adjusted...
plus high idle is harsh on an automatic transmission when engaging the gearsComment
