Few Simple Questions... I Hope..

Recommended Posts

Guest tommyboy205

ok..

first of all i am sorry for having to post these simple questions.there are quite a few and i figure they are gonna be answered easilly by someone, i get to make more posts so i can achieve 30 and get into that for sale section.. :D

 

ok.. i bought the car a week ago. havent had time to look at it or drive it till just now.. here is what i found..

 

from start up it idles low.. about 500rpm.. if you increase the revs and let let them fall off naturally, ie off the gas, it stalls.. does this until it is totally warm..

 

i ahve done a little search and it seems this is usually due to the sav (suppliment air valve?)

 

but..

 

i also discovered that there is a pipe off and some other suspect stuff going on around the inlet.. there are various breathers etc around the butterfly..

 

one comes from a little black canister that sits just above it.. i am assuming this is some kind of emmissions control or catch tank?? so one pipe off this canister (the right side one) goes to the inlet, before the butterfly... the pipe that comes off the right side is blocked off.. where should that one go to?? the car has had most the induction removed and a suspect k&n bolted on.. did it perhaps go to another part of the inlet??

 

ok... another..

 

back to the butterfly.. facing upward.. right ontop of the butterfly is another breather.. but it is open.. what should go to this?? now because it is open i am reluctant to make any other opinions about anything else until this is solved.. i suppose it could cause the stalling problems and it could be causing overfueling which is making a small puff of smoke on overrun at higher revs.. so what should be happening with this pipe then??

 

lastly.. (for now) is there supposed to be a cable for the choke or is it all controlled with the sav?? the reason i ask is that the pulley for the throttle has a second pulley wheel.. i assume for a choke cable, just behind it.. can anyone shed any light??

 

cheers for the help and understanding.. i do understand engines a little but each one is wired slightly different.. you might have to bare with me for a few months.. :)-_-

 

edit:: a high res pic of a standard engine bay would be excellent if anyone has one or a link.. cheers

First off the SAD or SAV is a common problem and is situated under the thermostat housing.

 

The canister you talk about is the oil filler and breather system, the one goes to the inlet pipe before the throttle and the other on the other side of the 'cap' sits on the open pipe sticking up on the throttle housing.

 

On the pipe between the airflow meter and throttle housing you have 2 pipes coming off it, the first one at the front should be going to the SAD and is fully open on the fitting inside, the other on the breather should be partly closed off when you remove the pipe, make sure these are clear.

 

Hope this helps for now.

injection engines, which i'm assuming it is from the description, don't have chokes.

pics of your probles might be helpful.

i get that injection cars dont have chokes so to speak but why is there a 2nd pulley wheel.. that was what i was trying o get at..

 

cheers for the link to the pic, saw that one on the forum main page but the area i need to look at is not high enough detail.. i will have to find someone with a car i think..

 

i will do an oil change and block off these holes etc and see where that leaves me.. i will try to find a car too look at in the near future also..

 

cheers for the advice and help..

The trunking between the AFM and throttle body should have two pipes coming off it, one goes to the SAD the other goes to the oil filler/breather.

The throttle body should have four pipes connected two it, three underneath and one above. The above one goes to the oil filler/breather. The two thicker ones underneath are coolant hoses, the third smaller one should go to the dizzy.

 

What RPM is your hot idle?

looks to be ok..

had a oil leak from the cam cover and i managed to seal that up. thought it might have been excessive pressure so i checked all the pipes as precaution. everything is hunk now..

even the oil pressure gauge has calmed down since the oil change i did.. it was a bit scatty before..

 

one problem left and it doesnt bother me.. the cold start is bad.. it stalls all the time.. fine after about 2 minutes though.. just have to keep the revs high whilst manovering in the beginning..

oh and a slight knock from the offside wheel when going over bumps.. bush?? tie rod end??

 

hot tickover is about 700 but after a bit of a thrash stays about 1000 for a min or so..

 

is that a issue? what are the problems with hot idle?

If your hot idle is higher than your cold idle then the SAD isn't operating properly or at all.

Check that its feed hose isn't squeezed shut, then check if it's pluged in. If both of these are alright than take it off and give it a clean, I've heard carb cleaner works well. If that doesn't sort it then it's probably dead.

ihave checked the pipes.. they are fine.. the wiring seemed to be connected atleast..

i will take it off and give it a clean as you said..

 

there are two bolts holding it on.. one on top and one hard to get to one underneath and to the back a little?? am i correct?

 

cheers for your help..
