please help

 

use WD40 and spray it all over ur manifold, then check for leaks, im pretty sure u will find it.

good link, but i dont have a FITV, its a spoon TB, it just has the 2 coolant fittings under neith it, oh and now it does it when the car is cold, and when i turn on headlights or heater, and it does it when the fan kicks on, but after all that seems to idle fine

 

bump cause i dont have the same hose on my b16 swap on the canister, but i have no irratic idle and it works fine

 

Any excess air that enters the motor can cause this idle surge. Vacuum leaks, IACV, FITV, EGR not seating when closed, bad PCV, throttle cable too tight, and idle screw out too far can all cause a high idle. When the idle exceeds ~1200 RPM with the engine warm and the throttle plate is closed, the ECU cuts off the fuel injectors. The idle falls below the threshhold, the injectors cut back on and the whole cycle starts over again. I had a starting boost valve(accord) that was leaking through the diapham that caused mine. Something like that can only be found with a vacuum pump/guage. Anything that has a vacuum line running to it can cause this problem if it won't hold vacuum, not just the vacuum lines and gaskets. This includes EGR diaphram, Boost valve diaphram, cruise control, MAP, Intake bypass valves, Purge solinoids and others. You need to set the idle to between 450 and 550 with the IACV unplugged. Plug it back in and clear your codes. If your problem IS something else, your not going to find it with the idle screw jacked out.

 

could it be timing? it seems like the dizzy is advanced ALOT

 

Timing is not going to cause idle surge.

 

how about the TPS? could that be it? when the took the parts off the other TB and put them onto the Spoon TBm doesn't it need to be adjusted?

 

No. Read my long post up there. Those are the things that cause idle surge. You've got an air leak somewhere. Have you replaced the PCV ever?

 

no, i just bought the car, and i bought it like that

 

"Any excess air that enters the motor can cause this idle surge. "

I would have to agree it's related to vacuum and /or air.

 

Here is what you should do....


1. Sell that piece of junk that you bought and i told you not to.
2. punch your self in the face.
3. Buy a new car so you dont have to go through these problems....

haha j/k cuz... i hope you fix it man. From what i hear your EG looks hella sick! you finally have a DOHC (been wanting that **** since we were 16) haha. and you Finally can rock SPOON stickers with out gettin made fun of for having all that POON **** on your car. Big ups for moving up in the world! Im out of this honda ****.

Spray the area with carb cleaner and see if it idles up/dies. Follow all the write ups and simple knowledge of diagnosing idle problems. People are helping you and giving you knowledge, use it.

 

sure enough it was the gasket.
