c20xe spluttering on low rpm help needed

**ccm640** · 04-02-2012 07:40

as tittle realie i have got a c20xe in my mk3 astra and yesterday on the way to work when eccelorating to overtake a lorry on the motorway the power just died and the car started jurking so backed of the power and applied it again and was fine 5 minutes later it started doing it again so had to turn around and head home joining back onto the motorway it done the same thing so gave it some hard ecceloration and it cleared and got back sound. after sitting scratching my head for an hour after getting back i went to investigate what it could be. i tested compression was equal and good across all 4 checked plugs all the right colour so connected a strobe to check leads they are also ok. what could this be? i think it is overfueling as does smell rich every now and then and don't do it when i put my foot down only when on lower rpm as if it flooding the engine what could this be lamber sensor? no eml on but does work as comes on with ignition. any help welcome and sorry for the essay

Injectors leaking? Seals good on them?

injectors are sound mate its as if its getting too much fuel as when i boot it it clears up and runs sound it only happens when going slow as if engine is getting flooded. its only started since tightening a leak i had from the valve on the fuel rail i'm just wondering if with the slight leak i had before was stopping this from happening and now its got full pressure its over fueling
