95% my AGU fitted to mk2 golf runs, starts and idles perfect but the odd time while driving it will feel almost non responsive and splutter as if its struggling but this is only when I give it a bit of oomph it it will drive okis/ not great when just touching the accelerator. when I come to a stop it wants a to cut out and it does if I let it. it feels like there is a struggle with fuel getting through the injectors but I'm not totally convinced as it's runs perfect majority of the time. last owner thought it could be a dodgy spark plug but I'm not convinced. any ideas ???
