| Standard TT rebuild is running very rich between 2000-3000rpm. Idles well and runs okay above 3500rpm. Oem injectors were re-used with new O rings. An EGR elimination was done during rebuild and I use a Zemulator with Ash program. I think leaky injector O rings may be at fault but the workshop says a couple of injectors are worn internally allowing them to flow more fuel than normal after cleaning. Is this possible ?
