General Air-box pipe connections

[spinfisher99]

Can anyone confirm the correct positions for the two micro vac. hoses that connect to the underside of the airbox of my Sei. sporting? What is the function of the sensor? in the air-box they connect to? I'm still trying to find the cause of my fast idle(1500-1250rpm).I found a bad vac. connection to the brake servo and this improved my braking,but idle still erratic and high!I'm going to take off the stepper motor and give it a clean up next. Cheers

Have you had a look at your idle valve stepper motor? Might be a good idea to try it with a different one. It's hooked up to the throttle body.

Hope this helps =)

Edit: Sorry, just read your post again, ignore what I've written.

One pipe to the map, one to the airbox thermo valve. If they are the wrong way round you will get odd things happening, but its usually a split in the map pipe or connectors that causes your problem.

and whats that "pipe to the map" good for????? i removed old airbox and that hose, is just.. disconnected, with covered hole - engine's running fine..

what's the diameter of TB gasket??? using 899's bob and need new one

 

[spinfisher99]

Do you mean the thickness ? There is a half inch thick plastic spacer between the TB and the manifold.There are paper gaskets each side of the spacer.I just drew around the spacer onto a piece of cereal box and cut them out.On my car if you remove the pipe to the map sensor the revs. drop and it idles roughly.

hm but all the ladz who are using intake kit must remove this hose-theres no where to connect it

i am using 899's tb bob and using also 899's airbox gasket(round rubber)but its in bad condition
