ok so when im coming up to a stop sign or stop light or just slowing down in general the car stalls out and i know that im in neutral im not in any gear and it shuts off like im turning the key to turn it off which i am not doing, the car turns back on no problem at all. i have no cell codes i have no codes stored nothing


things ive changed
Spark plugs ngk
Wires
Cap
Rotor
fuel filter
Ect sensor
timing belt
water pump
2 bottles of sea foam
Cleaned iacv
changed t stat
Bleed coolant until no more air was left
i swapped distributors with a known good one
ive done more just trying to remember i did a lot

 

had teh same problem today

 

help me out when you find out what it is

 

You may have to adjust the idle rpm. Turn on the car and let it warm up. If it's an idle problem it will shut it self off once it warms up and the rpm's drop.

 

ill try that now and let you guys know

 

Check out the iacv! also check for vacume leaks or loose vac hoses. my guess is gonna be with the iacv.

 

it may be my iacv when i went to unplug my iacv the car was warmed up the car shut off, i was trying to adjust my idle screw

 

FITV is another thing to look for. No luck with the idle screw adjustment? If im not mistake vacuum leaks usually result in higher rpm or erratic idle. His seems to sound like its just dropping to nothing.

 

my car is a 99 so i dont have a fitv and no luck with it because when i unplug the iacv to adjust the idle screw the car will just turn off

i forgot to say my car has an intake headers and exhaust

 

If its shutting off as soon as you pull off the iacv then it's not getting enough air. It basically bypasses the throttle body to let enough air for it to idle correctly. Perhaps there is a blockage in the throttle body? I would advise against cleaning it while still on the IM so not to get anything into the cylinders. Try screwing the idle screw towards the fire wall (counter clock-wise) quite a bit and see if the rpm is bumped up, it should even with the iacv still attached.

 

ive cleaned my throttle body couple days ago

 

Not sure then, it's definitely an idle problem, when the iacv is unplugged it should still idle just really low ~200-250 rpm.

 

yea i know that i think my iacv is just bad

 

i just got a cel code for 73 misfire in cylinder 3, 74 misfire in cylinder 4, and 45 fuel system to rich or to lean which i think is running rich because i cant seem to get rid of that cell, and my cars pretty much had a tune up maybe its because i got crappy wires lol but i do have ngk spark plugs

 

check you car for exhuast leaks.... could be why you are running rich

 

you know what it probably is that because my headers have a huge dent in them and my cat is welded shitty and so is my muffler and the bolts that hold onto the cat and header one is missing, owell i just ordered my yonaka exhaust and i got a itr header with a new stock cat

 

If you don't have a surging idle, and if the idle drops or the engine shuts off when unplugging the IAC valve, the valve is working.

Frankly I think that your base idle is just set too low.

 

how would i bring it back up? lol

 

ok so i found this
http://www.clubintegra.com/board/showthread.php?t=56657

i somewhat know what hes talking about but then i get confused can someone else explain it to me better lol

and with the allan wrench what way do i turn it

 

Threading other than specialty threads such as gas fittings are usually the same. Lefty Loosey, Righty Tighty. Counter clockwise is loosen and clocking wise is tighten

He said in the post that he did two full turns both ways then one full turn clockwise.

A red neck way of finding vacuum leaks is propane. I don't recommend it, nor endorse it. I've seen it done before and it does work but can be potentially dangerous. The theory is if there is a leak, the added propane as fuel will increase the rpm when it gets sucked in where there is a leak.

I still believe there is a problem other than the iacv, the idle adjustment screw opens and closes an air way separate to the iacv if i remember correctly.

 

hmm, maybe im leaking from my brake booster i mean i am pressing on the brake most of the time when it stalls

 

Are you nuts man???? You might as well use gas to do it lol

Spray a little brake clean around your vacuum lines, if the idle fluxuates you have a leak

 

ill try that this weekend

anybody else have any thoughts

 

I clearly stated that it is not safe. Its as safe as brake cleaner..... Brake cleaner is extremely flammable. Im not saying put a propane tank in the engine bay.... Use an extended hose with an easy on/off.

Edit - as least if your using a trigger style extension on a propane tank you can turn the gas off with a simple let go of the trigger, while if you spray brake cleaner everywhere you will have a fire. Propane is flammable but in the open air it burns off and dissipates quickly.

 

Use spray starter fluid instead of brake cleaner or propane. It works the same by making the engine change in rpm as it burns the fluid but is designed for the purpose of burning in an engine.
