right, ive swapped them over, run the car up to temp and let idle for 20 mins and the problem has moved with the injector. Thanks Ian, your help has been much appreciated. as much as i would like to get all the injectors cleaned/flow tested im just going to get the suspect one done for now just to be 100% sure. does anyone know anywhere that might be able to do this while i wait tomorrow. im happy to travel a reasonable distance.

Unless you wait for 48 hours, no :) That's how long a good ultrasonic clean takes. Send it to Chris Wilson and he'll turn it around in the time he says it will, but it'll be 4 working days minimum due to transit time and the testing/cleaning.

 

It's good news you've found the problem :thumbs:

injectors gone off to mkivstore.com for cleaning. i could actually blow through this one and not the others so im almost positive this has to be the problem. i'll keep this thread updated how i get on. Thanks for all help on this, its done my head in.

just to reiterate. i think this bit of fault finding advice from ianc should be made a sticky.

the injector was indeed jammed open. martin (lucifer) cleaned it and after some messing around with it managed to get it to seal. it failed the flowtest too but its back in the car untill my new injector arrives. This is the first time the car has driven like stock off boost since upgrading the fuel system months ago

so thanks Ianc your advice was spot on
