it takes about ten seconds to start from cold and runs lumpy for a few mins
give it a minute oh two it will start straight away and run fine

ive changed the cold start valve under the inlet but it is still doing it any ideas cheeRS

vroooom ptssssh

Best to unplug the cold start valve altogether for starters as it usually jus floods it...see how that goes.

When was it last set up?

Lee Reynolds

Yes as daft as it sounds unplug the cold start valve. Then get it set up...

chink

was set up about a month ago did it before that anyway but it was summer then and never took this long!

i have had it unpluged but im leaving for work just after 5 everymorning and it always trys to cut out when its cold

gup

iTrader: (1)

does it come on choke at all in the morning
and do you let the fuel pump prime before you start it

try putting some injecter cleaner down it too

also how you been lol

chink

yeh let it prime ive done allsorts even had airbox off and opened the flap a little on metering unit, cant understand why its fine when its warm

got a 1.9 for it now aswell gup, cossie discs to go on allround bigger cooler, lots of crome stripping a full s2

gup

iTrader: (1)

bloody hell dude you dont hang about do ya

sounds like you might need some injecters in thier dude

chink

well ive got another head stage 3 so il just run it till i but some new shells in the 1.9 as the oil pump has gone and spun a shell!!

got allsorts now buddy mahle pistons, stage 3 turbo needs a rebuild, cam with stage 3 head, spare box you know any one who needs any bits?

so why do you think its the injectors

gup

iTrader: (1)

oh oh i might be after some bits

sounds like the injecters are not holding thier pressure over night and the fact that they are about 15 years old

vroooom ptssssh

Cant be injectors if it runs fine any other time...?

Maybe got a small air leak somewhere that dissapears once its heated up?

I had a prob on my S1 simmilar to what you have, it was a relay that powered the fuel ECU for cold start and on boost fuel enrichment...a small glass fuse was blown in it and it had the same symptoms as you describe but im sure someone said the S2's dont have this relay, it was under the dash next to the fuel pump relay!?

gup

iTrader: (1)

only happens when cold tho fella


also is your car coming on choke

chink

i think its hit a miss with the choke cause if i go to set off it will pull away then bog down and ive gotta dip the clutch put abit more revs on and it will splutter ans clear up

gup

iTrader: (1)

it should still idle above a 1k when on choke (depends how it was set up)
until it warms then it will let the revs drop try taking the auxirlly (spelling) valve off and clean it up its the little round thing with 2 hard black plastics under the inlet

vroooom ptssssh

With my CSV disconnected, from cold it idles at 800....once warmed it idles at 1000...

What do you mean by 'on choke' gup?

chink

so how hard is it to change the injectors does the inlet manifold gotta come off as ive got a crome one to put on but was gonna wait till after winter when i rebuild the 1.9

gup

iTrader: (1)

ie it idles higher when cold (on choke)

until it warms up

just a phrase ive always used

chink

yeh seen that thing today cut my hand on it when i was taking the cold start valve out

chink

i dont think it does that uknow think it just stays ant 800 ish altime

gup

iTrader: (1)

s2 you can remove the injecters with only the throttle body to remove thier easy fella just becareful not to twist the fuel pipe when undoing them

also on the auxillry valve if you take it off completely

clean it and put it in the freezer for about 10 mins
the hole should be open if im correct

and when it warms up it will almost close the hole

or it might be the other way round ie
closed when cold and open when hot

vroooom ptssssh

Ah I see you mean on cold start, His wont idle higher when cold thou if he's got the cold start valve disconnected.

IMO it's something to do with either:

Air leak
Fuel ECU
or Setup

Turbosystems

iTrader: (5)

this man is correct
regards Tony Turbosystems

chink

so whats the auxillry valve do is that the choke?

will that stop it from starting cause if i un plug the cold start it still takes ages to start

chink

so do you think the same as gup injectors?
because if i undo the cold start its still the same

gup

iTrader: (1)

alright fella i thought the cold valve only works when the engine is cranking tho

chink

it does just puts a small squirt of fuel in i think

chink

if must do overwise it would be a injector sorry if im wrong

Turbosystems

iTrader: (5)

the blue cold start injector is not the cold start warm up enrichment .this is controled by your black fuel box and enriches the air fuel charge for cold start and warm up enrichment by controling the fuel pressure actuator on the metering unit and increasing fuel flow through the main fuel injectors.

chink

so is it worth trying that ive got a spare oh are they matching to the ecu

gup

iTrader: (1)

also have you checked to c if the metering flap is sticking slightly

try removing the a/f and get someone to start it and c if the flap goes down slightly

chink

yeh il try that but would it not do that when its warm aswell?

so if it does not go down is the metering unit shagged?

gup

iTrader: (1)

yes and no really fella ( on it being shagged)

you can adjust these to c if they are just catching the side of the hole

it should stick a bit when hot too unless its just all the shit resting on it over night

chink

well ive got a spare metering unit off that over turb, and a spare fuel ecu in shed and another on the car il change it tmr with the injectors and what else it needs lol

if all else fails il have to build the 1.9 tall block up quicker

gup

iTrader: (1)

try one thing a time fella try the ecu first


but if you change the injecters your gonna have to leave it over night to check to c whats its like in the morning

also rip the plugs out and c what colour thier are too

chink

i wont be out in it tmr night anyway got a 21st party then on sunday gotta go take the brakes and little bits off the over turbo

gup

iTrader: (1)

so have you bought this turbo or is it your mates one

Turbosystems

iTrader: (5)

stop messing with all these things fit 4 new injectors un plug the wire from the blue injector and check /reset idle co and base idle.

chink

the shell is fucked and oil pump went and its spun a shell and fucked a rod

i can have what i want for 300 quid everything else is going to scrap yard

got full 1.9 in kitchen in bits hehe

front mount cooler, box paddle clutch, spax suspension what im selling, exhaust whats for sale, all samco hoses all bling under bonnet discs allround, twin head lights what im selling you need owt? just taking whats worth abit little stuff like oil pressure gauges etc

chink

how do i check/reset idle co will it need a set up?

gup

iTrader: (1)

bargin fella get your bro round and tell him to fit it all into an xr2

Turbosystems

iTrader: (5)

yes it will need setting up make sure u use someone that knows about erst's such as turbosystems msd or karl norris to name just a few
your injectors are leaking they are worn and old common problem which causes start up issues that you described
