black 172 phase1
right got a 172 x reg 2000,when light throttle applied to maintain a set speed say 20mph ,car hesitates and stumbles,missfire maybe,but clears when throttle pushed harder through it,changed ngk plugs ,fuel filter, idle valve, lambda, coil pack and leads,and swapped with mates map sensor cold start sensor etc,still same ,plugged in to mates snap on solus no codes ,only thing left is injectors could these cause this issue ,if yes has anyone got a set with fuel rail for sale,i live chelmsford essex way so nearer the better cheers
