rite my s2 is holding back under load now and again its runnin a bar of boost chipped big intercooler air filter exhaust ect ect 1min will go like stink then it feels like its choked up done the plugsstill the smae dump valve was leakin disconnected it still the same.............. feels like the boost hoses are colapsing but it got silicon efforts on it..... any ideas???????

Rick

tighten ur knock sensor up, make sure connection to it is good. Green plug on righr of inlet.

GAFFA

not to sure but it might be the actuator fucked get a 31 fitted [/b]

grunter

its gotta -31 fitted and workin fine mate will give the knock sensor a try cheers

i had the same trouble in my first s2 and i turned out to be the ecu not advancing and retarding the ignition sometimes it would do it every now and again, i cured it bye cleaning all the conections to the ecu and re-soldering all the iffy lookin joints inside the ecu unit,....worked a treat!! give it a go ...nothin to loose..L

grunter

will do mate cheers also meant to add it seems ok if u dont use full throttle which seems rather weird to me

biglee

that would suggest either what i said earlier, OR your fuel pump not creating the full demand at full boost thus going lean...maybe.... more likely to be the earlier idea tho mate.

grunter

nice one mate thanks ill spend some time on it over the weekend ud of thought id of learnt buy now how much they rob ya after 2 rsts and a cossy lol

Rick

Get it to a tuner and make sure its setup correctly.

If your close bring it to me and ill check it for free

grunter

cheers jano just p.m'd u...... was also thinkin ig retard ma self but was also thinkin hoses after hearin wot sounds like air gushing out????? weird

withamxr

my s2 does the same but it has already been set

grunter

well its drivin me round the bend lol 3rd rst and neva had this problem grrrrrrrrrrr

SafeChav

Worth checkin the throttle position switch is working, thats what tells the ECU to give full load enrichment......nothing else. Common for the solder joints inside to break down and go dry, i had the exact same problem.

webby80

i got the very same prob wiv mine

grunter

ah ha now i was lookin at that earlier lol gonna try hoses see wot its like and then try other things

grunter

ok so ive took the top hose off its got oil init........ but im not burning oil just a litte puff on over run its still using a standard breather system and runnin a bar of boost so the next question is turbo or breather??????? i know on my cossie it was the breather making it smoke help

SafeChav

Turbo is my answer......oil in the CROSSOVER pipe and smoking on over run can be nothing but, theres usually oil in the lowest boost pipe, but to get it in the top one is something else......

grunter

tis turbo had the hoses off and theirs more play in the shaft than god knows wot........ tis all good though ive found my self a nice stage 3 turbo thats a year old and only seen 8k since it was built for 200 quid its a technics effort 2

grunter

road trip tonight off to fetch the turd blower just hope its as good as the dude says funny thing is now ive agreed to buy it shes not smokin or holdin back lol

SafeChav

Sods law

Rick

it's not the turbo that is making it hold back. Oil in the crossover is common - and defo isn;t the turbo, as the compressor seal doesn't leak. It's oil from the breather as it is plumbed into the metering head.

SafeChav

I'm not going to argue that cos he knows his stuff

grunter

not as much oil as wot was in mine mate it poored out when i took the hose off then wen i moved the shaft there was an amazing amount of play init.... also hen i start her up from cold u can here the compressor wheel hitting the housing oh also its used nearly a sump full of oil in 2 days if it still does it wen i put the turbo on then ill do the breather........ got some people tellin me the escort dont need a upgraded breather an others sayin it does wen running more than standard boost this thing has cost me more in 2 weeks than ive spent on my cossy in 2 years lol

SafeChav

Welcome to the glorious world of ERST's

grunter

yeah i know mate ud of thought id of learnt after the first 2 lol
