Hello mate
Found out today the new coil pack was very low spark on 4 and 5 replaced back to original and running better still bringing codes up. Swapped injectors over still backfiring but no codes really confused now

yeh i thought about that 2day it shouldent make a difference. im trying some fuel injecter cleaner at the min so will see what its like 2moz on way to work and also my diagnostic at work can do a intake vacume test apparently

Dont think swoping back to std manafold will help as said Iv got these manafolds on mine and its fine as long as the lambda sensors are pluged in should run fine

yeh strange on the fuel rail managed to stop the rail seeping with some silicon and managed to get a couple of new o ring so fuel leak stopped. still missing and backfiring doin my head in now

Hi dude sorry your cars not good and no mine runs fine all that happens is the adaptive fueling is running about 20% so all good ,Odd that your rail is leaking could be injector "o" rings you checked all your pipes ? just thinking about the one under the throttle body or the vac lines at the back of the engine.

hay mate nah shes still not right missing and backfiring got a tiny leak coming from the injection rail think its causing the prob got a 2nd hand one coming from ebay so fingers crossed
cheers for asking and once iv tried that ill let u.
did u have any issues when fitting your manifolds with running smoothley

hay dude hows the st is she running good?
