completely random, hot or cold, take away or eat now - behaving like no or weak spark - anyone else had similar troubles
small turbo model

UPDATE! - re-set the ECU (by unplugging it & seems to haev gone away! - weird)

sure its not plug gaps mate???

GAZ345

does the misfire go away after you have booted it ??,escos are bad for the lambda sensor sooting up if you don't boot them

red october

could be either - will check plugs this morn' but they have been there a while & had the prob occasionally with the last set - could well be lambda as the car does have to endure non booting quite often - cheers ppl!
not sure what i can do about that mind ???

ryan_belfast

Mine is the spark plug gap i think.

red october

anyone got opinions on best gap for stage 1 small turbo then ?

ajjames

mine is very jerky on light throttle and in traffic i have just been living with it but i would love to find a cure someone on here said it could be a throttle position sensor fault

Dave Henshall

stg 1 small turbo, ,: AGPR12PP8 plugs with a 0.8 mm gap

ryan_belfast

i was told 25-28mm gap for small turbos?

Dave Henshall

feck, thats quite a a gap, sure you dont mean thou
that = 0.6-0.7 mm,

you want as large a gap as you can run with , without misfires, start at 0.8mm, then if you have problems, yes drop down, but the small turbos run coilacks as std so shouldn't see many problems at 0.8 running std or stage 1 boost

as above

got a mate gringing a snap on scanner round soon - lets see what that says!
tried the fault reader & go confusign results!!

cheers all for plug gap info - will have a go asap

red october

has anyone else done the wired LED fault code flash test ? just did it & got very confused with the results lol

i'm sure the codes translated as:

1. you have a walrus in the exhaust
2. nothing wrong at all matey - car then promptly stalls & wont restart
3. actually pointed to possibly a bad earth or fault in the ISCV

most confusing part of operation (as u can probably tell) was actually reading the autodata book correctly & trying to decide between what 2 sets of flashes i was counting - hopefully get the man & scanner round 2morro or thurs & see what happens!

yes, i tried that a few yrs ago on one of mine,impossible to work out from the flashes and either everything was faulty or everything was fine,lol,got stuffed in the cupboard never to be used again!

still have an annoying 2000 rpm occasional judder but that has always been there - god knows what it is but all other fooking about has gone!!
SMART!

ryan_belfast

what you do just take the ecu out and plug it straight back in?

red october

make sure the ignition is off, remove ecu multi plug (you will need a 10mm spanner), give the contacts a clean while your there, plug it all back in again & hey presto, the stored faults in the ECU will be cleared!! (the EECiV will record & keep all faults & if said fault required it to adjust the mapping or something weird it will carry on with those settings!, at least that what mr spanner with scanner tells me)

another common place to check is the big multiplug under the bonnet on the passenger side flitch,make sure its not all corroded inside or full of water.

i have justbought a escort cossie and it does the same thing at 2000 rpm and he told me it was just the timing? and that MSD who did the stage 3 tune didnt have time on the day and would finish it for Ł45 but thats miles away and i am taking it to PTS to see if they can sort it out....but is this a common problem???????

red october

cars running with coil packs quite often get this problem it seems but i have heard it from dizzy jobs aswell ?????

like i said earlier WEIRD!
