Hi there Lads/Ladetts
As some of you know i have a new head fitted to me truck,have changed all the fillters/belts.And for good measure ran some WYNNS diesel conditioner through the system.Somehow now iv got what feels like a misfire or power strain when trying to pull away.this happens at around 3rd gear@35/40mph. or pulling away from lights under heavy foot etc....Any ideas lads...Thanks

you may be pulling air into the fuel system,just run through the fuel system and check all connection are tight.and that the injectors are tight.check the fuel rail washers are new and that its tightened down properly.were the injectors checked when the head was off?is the pump timing correct?check the correct fitment of all the vacum hoses?make sure theres nothing hanging off or missing?hope some of that helps.if not im sure someone will be along later to give more advise.

Air leak at the intercooler?

Air leak

Air leak at the intercooler?

Would it be the rubber conector at the bottom where turbo meets intercooler
or at the top where pipe meets intercooler or both

Check both anyway.
