Right Just finished fitting new injectors as they're needed for my next remap,
After fitting them I've took it for a run and car seems to judder quite heavily @.5bar I'm guessing this is due to the ecu not set up with the bigger injectors, (don't worry I'm not thraping the living day lights out of it before it gets mapped just making sure it drives after I had it all stripped), Also the car seems to start poorly compared to before it seems to just about fire now then pick's up the revs to normal idle speed, I'm hoping this as something to do with the bigger injectors.
The only thing I may have screwed up on is there is a valve just behind the alternator for the Fuel breather, On the front of it there is an arrow and EG printed on it at the moment the arrow points towards the air intake pipe. Can anyone confirm this is right?
The car is 03 STI Uk.
Sorry for the long thread. just wanna get all the things across.
Cheers for any help.

 

your car will not run or perform at all
be cause ecu thinks thats in still have standard injectors
i would not even drive the car at all,
i would go and get the car re-mapped asap or i would say you gonna have problems
if you are planning on driving it around no at what speed you do i would put the standard injectors back in until you get it mapped

 

I'm not using the car till it gets mapped hopefully next week, can anyone help with the EG and arrow on the one way valve just to the left of the alternator with three vacum pipes off it, I'm presuming EG stands for engine??
Thanks.

 

Just had a look. EG with arrow goes to the induction/intake pipe. the singe one with no pipe opposite goes to inlet manifold and the one into the arrow(eg) is from under alternator somewhere. didnt look to closley down there. Hope that makes sense

 

Thanks Turbotits , Have got it all right after all, Spoke to my mapper and said it all sounds normal after bigger injectors chucked in, Oh well few more days and it'll be sorted.
