My 1st RS turbo question

The car's idling around the 2.5 mark which sucks the big one!!

The idling screw is all the way in so it cant be adjusted anymore - anyone got any ideas?

Problems already eh? nice one

Physio

Yes Steve


NUTS RuS longer screw in the metering unit?

Lambchop

Look on the bright side mate!! This car is going to save you money in the long run! You arent gonna want to sell the evo anymore and lose money buying something else before realising evo's are best and having to buy another!

Physio

You could well be right geeza

Try turning the screw down on the left hand side of the throttle body?? The one that puts tension on the cable.

Physio

Tried that too

Jim Galbally

ah, so you've got a nice airleak somwhere, and the idle mixture screw's been wound right in to put enough fuel in to stop it stalling

start spraying stuff near bits that leak

and without trying to cause offence to Roosie... check everything's connected up the way it should be, dumpvalves, bleedvalvles, actuators etc.

NUTS RuS

Cant believe you fell for it

Physio

I'll have a look today to see if i can find a leak anywhere, it rev's high even with the mixture screw taken out

Physio

When you push the flap down slightly in the metering unit the rev's do drop down so i thought you was being serious

Roosie

iTrader: (8)

think you might find the servo might be leaking were that shitty joint it.
there is no bleed valve and has a new pipe on actuator to turbo.

dont rst's stall if theres a air leak on the boost system ?

Jim Galbally

jay, not if you put the fuel in to match.

the screw on the metering unit lifts the flap up more (or down, cant remember which way it is on KE) in its rest position, making it add more fuel

it could have an iffy metering unit, take it off and make sure all the moving bits move freely, and spray SHEDLOADS of wd40 on anything that doesnt move like it should

mk2rstaff

must be an aqir leak that, try spraying colld start around the inlet and see if it changes the revs any

Physio

So if the flap in the metering unit is pushed down that add's more air & less fuel?

Ginge !

spray brake cleaner around places and see if the revs rise, when it doe then thats where the air leak is

exactly as jim says apart from dont spray the car with wd40,, brake cleane evaoporates and wd40 with stay there atracting all sorts of dirt/grease and shite and you will NEVER clean it all off


good luck

Jim Galbally

flap gets sucked down to add more fuel

Physio

I better get down to Halfrauds & get some brake cleaner or cold start - whats gonna do a better job?

mk2rstaff

cold start mate it just evaporates away, but mind not to use to much engines can get seriously addicted to it

Ginge !

aj the both do the same, we use brake cleaner at work as we got fucking boxes of the stuff and its 50p a can

it evaporates and makes the revs rise when spraying the engine bay,,,, oh and also helps to clean the engine bay aswell and blows out dust ect

so IMO use brake cleaner,,,, but that is just my opinion based on my experience

Physio

But when i push the flap down (open) the rev's drop down

Ginge !

aj have you ever thought about buying a reliable jap car ????


this is the reason why i ALWAYS recomend a efi conversion

check the breather pipes theres a t peice near the metering head that comes undone and what happens is you get a anti lag effect when you change gear,,, people adjust shite to hide the bad running rather than spot that fault

i hear evos are decent cars

Jim Galbally

thats because it'll be overfueling when you push it down too far

the amount of movement you need on the flap is TINY

i'd deffo be checking for an air leak... oh, and check the timing whilst youre there, it might be too far advanced to try and cover the airleak too

Physio

Anyone want to buy an S1?

Jim Galbally

seriously aj, if you cant find the problem, get it down your local bosch specialist, there are loads of em out there.

just gotta find one, who hasn't forgotten how mechanical injection works

mk2rstaff

never raced or rallied one careful owner

Ginge !

erm jim,,,,,, you HAVE met aj havent you

HOW THE FUCK IS HE GONNA BE ABLE TO CHECK THE TIMING

hes not a car mechanic so doubt hes gonna have a danny how to check and asjut the timing on a mfi car,,,, theres techs at my work who dont know how to do that


aj be carefull when pressing in that flap,,, dont want you getting sucked into the engine

Physio

ROFL

Ok so where do i start?

Do i get a can of petrol first & then a box of matches or the other way round?

Jay,

iTrader: (4)

petrols good
ginge is right brake clean and check all fitted hoses remove and blank the wank valve if it aint that then it might need the metering head serviced

Charlie Chalk

iTrader: (1)

just leave it

Ginge !

EBAY IT

can i have the coment of " ginge is right" framed please

Stu.H

AJ, Im sure someone said it was running massively rich?

Would this affect it?

Physio

I thought it would but i've messed with the mixture screw in the metering unit & it doesnt make any difference

Jay,

iTrader: (4)

er no coz we think that you have been possed by chip at this very moment and that normal service will resume

Ginge !

if its running rich it would rev higher as such,,, more likley stall due to flooding

have you tried to convert it to cossie management
