I changed my fuel filter and cleaned my iacv changed the hoses that run from the fuel canister to the im (intake manifold) and now my car wont idle at all even if i put it in neutral it will die out can some body please help me out doesnt matter if car is cold or hott it wont idle... its a 90 crx with a b18a and b16 head... vtec is not wired up.. umm was working before these things were changed...


please help me.......

 

some sort of vacuum leak. most likely a problem with your iacv

 

so now my iacv needs to be replaced??

 

Make sure it is getting the proper air flow. Is the intake duct sealed. The fuel pump good. My dad had a problem with his catalyst converter not getting the proper air and now it wont go over 25.

its possible, but first make sure everything is hooked up right. is the IACV plugged in?

 

yeah plugged everything back in when i start it it will idle then as soon as i give it a lil bit of gas it will rev up then die out wont correct it self to hold an idle

 

the screen on the iacv was black really dirty took quite a bit of brake cleaner to clean it... i let it sit for about hr or two then put it back in and started it up ran fine but as soon as i gave it a lil bit of gas just died out

 

mine does the same, did you ever fix it?
when i gas it alittle the engine will just stall out. if not it will idle ok.

 

well runs fine today... kinda bogs out and hesitates when i let of the gas but it will recover and regain idle i know my air to fuel ratio must be jacked...

 

ill take that back as soon as it warms up to normal running temp no idle i think its my iacv is there anyway i can service it instead of replacing it?

 

I doubt it. I think the seals are what go bad on those, and using harsh cleaners might cause some damage to the seals, but its always worth a try.

If it were me I would try cleaning it out one more time. I found that pressure really helps when cleaning the IACV either from the aerosol or copressed air

 

bump ill try cleaning it again and hopefully that will fix things dont really feel like buying a brand new one there pretty pricey

 

cleaned it again an blew air through it let it sit out all night then put it on and fired it up will idle but as soon as u give it gas it wont correct itself and hold an idle it will just die.... so where do i go from here what are my options ??

 

im going out on limb here but check ur ecu for codes. ysterday i was coming home on the free way when all of a sudden my car started bogging down and almost die when i gave it gas. well after driving the CEL came on so i barely made it home and it read code 7. TPS. so i unplugge it blew out any possibldirt in the coonections made sure all the wiring was good. plugged it back in reset the ecu and ran perfect

 

yeah i had the same code today... actually i did the same thing and still was bogging down bad so i just adjust the idle and now its up and down but at least its not dying out gotta wait till pay day and im gonna get a new tps and iacv gotta unless my friend will let me use the parts and pay em later

that could also be the FITV, when they get out of adjustment they can cause the idle to bounce around.
Look through the faqs for the write-up on adjusting it.

wow you kinda described what is happening to me.

i did try to clean out the aicv and the fitv but the idle just stalls out.
no bouncing anymore after i replaced the tps sensor.

i also tested out my iacv. at this point i just ordered a new fitv and a aicv. i dont think that even with the testing it will work correct. because the symptoms occur after the car is very warm.

during the cold the symptoms wont show. when i tested the aicv it wasnt warm. so im thinking i should just replace it.
