[Pete_gti]

hi all can any one help me with my golf its a 1999 Treg 2.0 8 valve its on 75000 miles and has always been serviced on time and has neva missed a beat until know . The problem is as follow when driving and your in a hi gear and you say slow down for a round about but dont change down a gear and put your fut down its misses and stutters but its doesn't always happen i have put my scanner on it and cant get a fault code and the engine management light doesnt come on i have replaced fuel filter, coil. leads,plugs have removed and cleaned injectors but still happens i was thinking temp sensor but i thought someone might be able to shed some light on my nightmare

Must be a common fault that mate mine is exactly the same and i cant cure it ive tried plugs ,leads coil pack and fuel filter and it solves it for a while but then comes back,any way ive asked a machanic and he reckons there might be a bit of crap or water in the fuel tank or the fuel lines thats getting threw so might be worth a tank drain
