will this effect how the engine runs????

civictildeath

think it will take longer for engine to warm up

It probably will, unless Honda/Acura felt the need to include parts that don't do **** for the engine except raise its cost.

The FITV is there to help out the cold idle - if you remove it, or 'fix' it (which disables it), then you won't have the functionality it once was providing.

I definitely have to agree with this statement, but other than that, I have had no problems having my FIT valve blocked off. Don't get me wrong, it's a "remove at your own risk" situation, and different people have different results. I have had no ill effects though.

its not going to affect the warm up its just going to make your car run at high idle all the time. thats it.

My car idles just fine. about 1500 (maybe a little less) for the first couple minutes while warming up. Once it starts warming up it drops to about 650-700. But like I said before, it takes about 10 minutes to warm up (45 deg. weather) if it just sits there (I don't drive it).

Just find a used TB and bolt a new one on...

well I have a bbk t/b on one of my other cars and it comes with a block off plate so you can either run it or not, and I'm finishing reassembling my turbo crx and I broke one of the fittings of the fitv, so i was just going to pull it off

If your car idles high all the time after removing the FITV, something is wrong. Did you seal it off properly?

With the FITV my warm up idle was up past 1500. That was a little dangerous and annoying. After I bypassed/removed/blocked off the FITV, warm up takes a little longer but the high idle is at 1100 and drops to normal idle after I drive the car a bit. About the same as every other car I've driven. No loping or anything as some people who do the bypass incorrectly complain. Seriously, start your car, wait 15 seconds, then drive it easy until it reaches OT. Once your car is moving, FITV is irrelevant. It only warms up your car faster than it would w/out it if you sit at idle for most of the time your car is warming up.

Honda put it there to warm up the car faster and to thaw the throttle plate in freezing climates. I don't know why people always revert to the argument, if Honda put it there, you need it there. Honda put the stock exhaust and intake on there, remember? Honda put those 13 inch wheels you have stacked in your garage, with that shitty ***, what, Michelin? on them.

well I live in new engalnd so I guess I really should fix it, but thanks for the info.

Mine has 2 ports on it. Is one a coolant in and the other a coolant out? I just did a swap and I am leaking coolant from that line. im almost positive my lines aren't set up correctly.

funkfnamna

one should be coming from the thermostat housing or the intake manifold, going to the FITV, the to the IACV the then to the metal water hose beneith the IM

GWInquisitor14

the way i have it setup right now is one goes from the thermostat housing to it and the other goes from it to the intake manifold. The IACV has one going from a pipe by the block to it and then another going from it to the throttle body.

GWInquisitor14

is this correct?

what is your setup? it sounds correct

LS/VTEC B16 onto a LS block.

I have my FITV blocked off and my car drives just fine. It does have a rough idle when the car is cold, but otherwise when the car warms up it is pretty much perfect.

boostedcivicsir

probably wont idle cold.
did an str throttle body for someone and it didnt want to idle cold.

funkfnamna

What gen b16 manifold? either way you should have one running from the metal hose on the back og the block that comes from the water pump to the IACV then to the FITV then to the thermostat housing or the intake manifold. It all depends on year and model.... I live up here in the northeast so FITV are a must. sitting in your car trying to warm it up when its -10 sucks.

i bypassed my FITV and my idle is really really low when i first start it up and then after it warms up it only goes to about 400rpm and when i mess with the idle screw and cable it still wont turn it up. its really weird. i also have an engine light on for IACV as well but ive gone through just about every process thinkable to try and fix it. i have a thread on it if you search my name you can find it (if interested). im probably gonna end up takin my car to a shop and have them test the wires in my wiring harness.

ek99

Are you sure its 400rpm's? Because the gage only reads from 500rpm's and up. One sure way of raising your rpm is by turning the little bolt on the throttle body by the throttle cable with an alen wrench. Unlike the idle screw, this will raise the idle for sure.

funkfnamna

yeah but he still has a check engine light. I would test the IACV circuit and the valve. heres a good writeup on idle problems

If i remember correctly, the manifold and TB are off a 91 JDM B16a1. The FITV is mounted on the bottom of the intake manifold. I have one coolant line going from the black line on the back of the block to the IACV then one from the IACV to a nipple on TB and then one going from another nipple on the TB to the FITV. I came to an educated guess/conclusion that the two nipples on the throttle body were a easy way to run lines around the intake pipe, so thats why they are there. Then another going from the FITV to the small nipple on the intake manifold. Then another (probably irrelivant) going from the thermostat housing to a metal bypass line to a nipple by the upper radiator hose.
