hi all, i have just got a 2002 51 plate sti type uk and had it for about 3 weeks now without any probs............ till now.
drove to work this morning and all was fine, coming home tonight and the engine management light came on.
now all seems to be running fine, revs round ok and does not seem to loose boost (no gauge yet) but light will not go off.
the car has a full 3" turbo back full de cat exhaust and have read that it can take a while for the light to come on after you take the cats off. is there any truth in this?
cant get it into subaru till monday so have to try get in somewhere else. any body any thoughts?
cheers, shawn

 

Has it been decatted recently?

 

not sure, was like that when i got it and think the guy knew nothing of them. as i say car seems to be running fine just got that on, i mean what could of happened while it was sat there all day doing nowt lol

 

Noticed your based in Huddersfield, dont waste money taking it to Subaru pop it down to Chy at Pennine Subaru in Hebden Bridge 01422 845007. Charged me aroud a fiver IRC to clear a CEL

 

nice one, jsut had it looked at by an alfa specialist, said it was a misfire on cylinder 2, re-set it and no sign of it coming back and light not on either.
whats all that about then

 

without the cat's on it'll keep coming back.. only way to get rid of it properly is to have the trhesholds changed which is easily done my a mapper..

 

the missfire?

 

No shawn, I think Fizz meant the CEL light

BTW, big up to the Alfa, er... *** Subaru specialist

 

This can be caused by a faulty neutral position switch - sometimes they incorrectly reports faults. Common problem on bugeyes, including mine.

The part only xosts about £35 to replace.

 

slight thread hijack apologies to the OP what is the Neutral Postition Switch?

 

When one defects to Switzerland... or becomes a LIb Dem MP

 

what he said.

 

It's a switch which reports that the gearbox is in neutral - in the bugeye it can often trigger incorrectly, especially when pressing on or on bumpy roads. For some reason, this shows up by lighting the CEL and reporting an incorrect misfire. It doesn't actually seem to cause any problems apart from this. I think it's in/near the gearbox.

I'm sure someone can give a better explanation!

 

thats interesting. can anyone shed any light on this?, just seems strange that it read a misfire when all seemed ok.
