i have a 98 ls integra. I am having the same problems that everyone is talking about in this thread. erratic idle, sometimes pegged at 2000-2500, sometimes fluctuating between 400-700. also, i have no part throttle. unless the pedal is at least 3/4 the way to the floor, it sputters really badly and is completely undriveable. then once i floor it it surges and powers out of it like it was bottlenecked. if i floor it the whole time it never hesitates. only with part throttle. i just took a look at the throttle body, and I do not have a fit valve. there are two open-ended pipes that are underneath the throttle body that have nothing hooked up to them, but i did not feel a vacuum on either one. (and while checking them i electrocuted myself somehow... dont know how... maybe on the distributer?...makes me wonder if there is a voltage issue) and looking inside the throttle body, there is only the one hole for the iacv. no hole for the fit. in the haynes manual for my car, it says the fitv is just to the right of the head breather. i dont see anything there. i disconnected the map sensor to see if there was a change, and the car immediately died, so i can assume that is fine. there is another sensor directly on top of the intake manifold that i'm not sure about. it is not labeled in the haynes, and it did not effect the idle at all when disconnected. and the car is throwing a system rich cel as well. my next step is to check the iacv. should my car have a fitv? i just swapped a b20b in, but the original b18b im is still on. i never had this problem before the new motor was installed this week, so it seems logical that they did something wrong in the install. whats the next step if the iacv is good?

my prob
OK i just bought my 97 accord witha h22 swap in it. when i got the car the girli bought it from said that it had a prob with one of the injectors. the injectors are fine. when i started the car i had to keep giving it gas to keep it running. but once it warmed up it ran fine for i lil bit. the other day my car would start and then it would rev ral high and go back down. I looked on my IM and there was some kind of sensor that was lose and sucking air. I bolted it back on and it fied the rev prob but now I start it and it wants to die and some times it idels fine. then i give it gas and it wants to die and then picks right bac up. what could it be

Clean throttle body/intake manifold, see where that gets you.
I have a 1994 Honda Civic EX with a D15B VTEC engine and it lopes when it idles and when I put my hand over the throttle body it doesn't stall, it just keeps running so I think it has a vacuum leak somewhere but I just can't find it and it sucks ALOT of air through the IACV hole but I have changed the IACV but it still does it. It even does it when he IACV is disconnected but not as bad. I can't take it to a dealer cause it would be a fortune to fix it.Can anybody please help me? It gets tiresome sitting at a complete stop pulling out and it jumping all over the place!!!! Thank You here is a pic of my Honda.
well i tried it and it fixed it for about 2 hrs, but started back what's next? and also my brake fluid keeps backing into my abs reserviour. please help 1 year and running on trying to fix the bugs...1
So I went through the steps here this weekend, FITV is definitely not getting out of the way and results in a jumping idle from 900-1600 or so and sucks the entire time.
So I know my one problem, and am waiting on getting a new FITV valve, thanks for the excellent write up.
My second problem is that the car has taken to just randomly dieing as you are driving down the road. No check engine light has come on. It has died when running at 3000 RPM and at 4000RPM. Sometimes it restarts on compression other times I have to wait 5 minutes then the thing starts fine. Are my problems related, or thoughts, theories, wild guesses?
i think its a strong posiblity that my FITV is messed up. My car wont idle or start after it warms up? is is posible that i need to do the with my fitv
I believe the IAVC and the FIV holes inside of the throttle body are different on 89 Accord which is what I’m working on. When I apply my finger on the top hole, vacuum pulls through the FIV. I need help from someone to confirm that this is correct on the 89 Accord. This parts cost to much money for me to just take guess. Thanks
I never took the time to become very familiarized with the accord line of engines, so I do not have a good answer for the above questions, I apologize for that... However I can refer you to someone that knows; I suggest "female four", she has appeared to be very knowledgeable on the accord engines in the past, she should be able to help you.
