What the hell attaches to this ???

[grinder]

Hiya chaps - was gonna post this in the 2nd gen section - but thought it would be better suited here

right then , this is the story so far

1 - bought an 88 turbo cab
2 - it idles really badly - but revs fine
3 - not been driven in months ( i dont think )
4 - refitted the exhaust as its making one hellofa noise and spotted this ( see attachment )

so ... what should connect to this

me and brett have been discussing this for days and no answer ( as yet ) - its nothing to do with the air pump as the 2 pipes are connected to where they should be

and i cant see for the light of me what is supposed to connect to it - it looks like an air valve- so this could be screwing the idle

HELLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLP :)

Thanks chaps

stu

( sorry about the size of the pic - but it makes it easier to see )

[grinder]

ANYONE ????????????????????????????

gonna cross post in the 2nd gen section to see what happens :D

[Iwan]

Hi,

if you mean the connector, this is going to your O2 sensor (Lambda).

The 4mm hoses are attached to upper manifold, blow-off and the map- sensor.

[grinder]

yeah i know what they do !! :D

if you look behind the 02 connector - there is an open pipe ????

if you look at the pic you have ( in a line )

1 - o2 connector
2 - 4mm black pipe
3 - open hose
4 - black pipe - red stripe
5 - bov

its point 3 - i have no idea what SHOULD connect to it

i will try and get a better pic !!

[grinder]

not the best pics in the world - but may highlight it a tad better :D

[mullins]

The clear hose?? What does its other end connect to?

[Iwan]

not the best pics in the world - but may highlight it a tad better :D

Hi, Ah ok....

I will check the hose routing on my car this days and will post results here.

The other pleace you have marked stay clear. It is not attached to anywhere.

REgards
Iwan

[grinder]

so its just an OPEN OUTPUT ??

i have looked in the manuals and there should be a pipe connected to it - problem is - it doesnt tell you what pipe or where the other end fits :(

Mullins : the clear hose is the boost gauge pipe and is OK !!

i dont know how to get a better pic - thats probably the biggest problem :(

[Brett]

We think it should/could have a connection from there to to the standard BOV.

[grinder]

i dont think so matey

the stock BOV is fed from the intercooler piping - and the bov that on there still takes the same feed - its just that it vents to the air rather than back into the air box

so keep these ideas coming :)

[FD3UK]

I have just checked that port on my air control valve, which has been removed. It is blocked off so is not a problem to leave open.

Not sure what it was for, maybe a requirement for non turbo car or US spec???

sorry about the photo just a snap from my phone

[grinder]

yours is blocked off - so not loosing air out of it ( he says knowing nothing about it ! !)

mine is wide open ??

[FD3UK]

Yep, it is blocked off, no it can't leak any air (mine deffo won't it's in a box of spares :) ). It is factory sealed not a mod. If you look at the photo it is about 40mm inside pipe exit. I guess it is a bit difficult to see still on car, but if you check yours with a pencil or such like it should come to a dead end.


Kev

[grinder]

ahhhhhhhhhhhhhhhhh will check that tonight :)

i have look in the manual and it looks like it should have a pipe connected to it

i wonder if it has something to so with it being a Jap car ???

will report back tonight.. thread will be...

"snapped a pencil in a pipe - ideas on how to remove"

LOL

[grinder]

well just stuck my finger in the hole and it feels like its blocked up

so onto the next question - why does it idle so bad :(

[Iwan]

Hi,
they could be many reasons for bad idle.
On 85-88 cars, the TPS can be faulty resulting in strange behavior of engine speed and idle. Check your TPS settings with voltmeter, but do this when the engine is realy warm! Othervise you will end in wrong results.
Maybe you have a vac- prolems? Faulty gasket? Or the previous owner did put the BOV on the car and forgot to block the hole on air induction pipe (the one from AFM to Turbo). Or your AFM is faulty or stuck.

[grinder]

the air pipe is blocked ( i think )

humm tps - will read up about that

the thing is here - i cant get the car warm - it wont idle that long :(

[FD3SNuttah]

i bet the tank is empty of petrol. try putting a fiver in, mine wouldnt idle as the fuel was too low.

[grinder]

yeah not a bad idea actually .. the fuel light is on - and its stuck on ramps aswell

i may chuck some more in to see what it does

ended up siphoning a gallon out of the coupe last time !! :D

LOL :-D

will start not that complex next time :P

PS. open your tank and remove the fuel-pump assambly. There is a filter at the end of the pump, which is probably clogged, replace this one and you should have no probs on fuel side. (maybe you have the same problem due cornering when the car stalk ?)

Its not part of that secondary air system that these engines have is it ?

Taking a look at the manuals that I downloaded from the 1300cc website, the pdf of the air cirtuits looks pretty complicated :confused:

It seems these are no longer on that site, but if your stuck for a copy, I can email you the section 4b which is for the Turbo car. The Haynes guide has some of the diagrams in as well.

Seems there was a lot of extra plumbing to get the car through emissions in the US - some of it can be removed. ;)

I had an idle issue which turned out to be the inlet gasket - so it could well be unmetered air getting in !

Good luck in finding it

Cheers,

Prof

[Prof]

Try here for the manuals - I am doing a weekend at work and got bored !

http://www.rx7city.com/techconnect.htm

[grinder]

thats prof

i have ALL the manuals at work for every Gen

i think its gonna be a "take it apart and see what happens !

i forsee a long project with scraped knuckles to be honest :(

[Grizzly]

On my car this had a pipe coming off it to a plastic charcoal filter type thing under the drivers side innerwing.

My vert had one untill i fitted all the block off plates.

[Grizzly]

So does it still sound like the exhaust is blowing? What happens? Does it start ok? or take alot of turning over? once its started does it run ok then get worse or bad from the second it fires?

Have you checked you have good comp? Do the top plug out and turn it over thing. You should have three nice loud and even PHssss noises.

[grinder]

right ..

1 - it will start and run - just
2 - as soon as i rev it - it then stalls
3 - there isnt much juice in it
4 - not compression tested it YET - cant find a tester
5 - the pipe for the charcol thing it fitted to another pipe ( dont forget its an S4 , not an S5 )
6 - i know my TII doesnt have this on the car
7 - it still sounds like its blowing from somewhere .. just no idea where
8 - we did a very very very basic comp test on the front rotor - it looked like a tire depth gauge - so you couldnt really tell - and the answer from that was 55 - just no idea 55 of what though !! LOL - although that could mean 4bar - which is uber bad

thats about the size of it at the mo - im not gonna do anything until i comp test the engine - which could take weeks :(

this car might not be as cheap as i thought ... :(

[Grizzly]

The easy way to make sure its got enough comp to start is take the egi fuse out, then remove the top plug of the rear rotor. Turn it over on the key.

You should hear even Pshss noises. when you have done the rear replace plug and do the FT rotor. much the same nice even Pshhh noises.

If all that is ok. I'd remove the IC and check the rubber hoses etc for leaks. if there is no Big holes in anything, Try swaping the plugs from your Coupe to the vert and try it.

[grinder]

chris - i was thinking the same about the plugs to be honest - brett says the make a world of difference

not sure what to do

1 - hunt down the noise
2 - get it to run

i will try the psssshhh test - sounds like fun ! :D

[Grizzly]

yep do the Pssshhh test then you know the engine is good.

Plugs

Check for split IC pipes etc

If i was you i'd be removing the turbo and get that sorted.

[grinder]

but i dont know if it is the turbo matey ????

to be honest - i bet i could walk outside now and it would fire no probs

its a bugger to start after its been running though .. again this could be crap plugs

i had to start it last time ( after it stalled ) by clamping the fuel hose

a better desc of whats going on

1 - me and a friend put all the exhaust back on
2 - started her up
3 - first touch , no revs
4 - was a bit lumpy
5 - goes to back of the car - check the exhaust , they are fine and sound ok
6 - car still a a bit lumpy
7 - quick stab of the throttle and she reved straight up , sounded fine ( just noisey )
8 - let go of throttle completly
9 - revs fell to 0 - therefore it stalled
10 - if it was only on one rotor i wouldnt expect it to rev that freely ??

does this help :D ??

if it was only on 1 rotor would it be vibrating really badly ?? - it wasnt - im just asking :D

because i cant get it to idle that well - i cant set the tick over - i dont know if to just turn it up slightly and see if that helps

all i can say - is that when we bought it - we jumped in , fired her up , drove her down the street and onto the back of a trailor - would this be do-able on 1 rotor ??

the guy said it drove fine , just sounds bad

now Adam confirmed this , he said she ran bad at tick over but would drive at 70 all day long ?

and he did say that it quietened down when the car had been ran - although i though this may be bad as when it warms up - metal expands ??

[Grizzly]

Usaly if it runs for a while then dies it means its getting too much fuel, it may be becouse the plugs arn't burning it properly or you have a leaky injector so it over fuels?

As its been stood for so long i'd tend to say plugs

Try running it out of fuel by pulling the EGI fuse whilst its running. See if it starts any easyer then?

[grinder]

well finally got the car to fire up and idle - the most simple of simple fixes ..


you will like this ..



put the plug leads on the right way !!

god knows how it did run - but now its sits at 1100 rpm and ticks over , what a difference , i cant believe how the plug leads were on , the T1 coil went to the L2 plug etc...

took them all off , colour coded them with tape - put em all on and she started up fine

still make a bad noise - but she runs

gonna give her a gallon of juice tonight and see if she will tick over and get warm

Stu / Grinder

[thebandit]

:D The old plugs hooked up the wrong way trick eh?! at least the problem is sorted :)

Took some pics for you of those rear lights if ur still interested? will get them up tonight if you like?

[Prof]

I guess if at least 1 of the 1's (L or T) and 1 of the 2's (L or T) was on the right rotor housing, it might just about fire ! :eek:

Still - good you found it - You should go and have a drink to celebrate :guinness
