helloi have a 2000 em1 and i just recently started to have idle surges. i cvhecked online and they said to check the FITV. when i took off my intake and car is warmed, i looked inside my throttle open area and saw that there was only ONE hole on the left hand side. i plugged the hole and my car died. does this hole go to the IACV? i detached the iacv and wiped the srceen down with water. still same problem. i tried checking all hoses for vacuum leaks. couldnt find any although i will replace them later today. also under my throttle body there is NO FITV. its just the TB thats it! please help

 

also, sometimes the idle needle goes up and down and sometimes it doesnt but i can still hear the engine's idle surge up and down when the needle stays stable

 

disconnected IACV and turned on car, the RPMS shot up to the sky. this normal?

 

here some vids, in the first vid after i went outside, the idle went back to normal but when i was inside the car you can HEAR and SEE that the idly is bouncing up and down

 

this video shows that i have NO FITV, just that ONE hole and when i plug it, car dies

 

you don't have an fitv... your not suppose to have one on an obdII car, clean the iacv thoroughly follow this link https://honda-tech.com/forums/acura-integra-6/%2A%2A%2Ahow-clean%2A%2A%2A-your-iacv-k-idle-air-control-valve-1575913/

 

check for vaclume leak,clean your iacv.hope that works if not you got to track down the problem anything from a leak to maybe a gasket like the intake mani.

 

is there any other way to check for vacuum leaks other than trying to feel for air coming out of the hoses? so far everything looks good, what other hoses should i be checking besides the brake booster vacuum line? and is there a more efficient way to check for leaks?

 

and maybe my IACV is faulty? how do i know if it is or not

 

anymore suggestions?

 

hrmm i read the write up above and i noiced i lost and dropped the IACV gasket that presses up against the TB. any1 know if i REALLy need that? any1 know if i can buy it separately? thanks
