Yeah you do need to set up your plugs ....look in your haynes manual (cav gsi) and you will find the correct spacing for your plugs.. yet .. its not a very good service if the garage didnt do this for you .,....... Other than that .....it may be an exhaust gas sensor problem or a catalyst problem ... do u have a standard exhaust .What / how old is your cat .My m8 had the same problem with his XE ...The engine will cut out under any sudden acceleration .....so i think maybe air intake sensor , exhaust sensor problem ,plugs or catalitic converter problem ............hope this helps !!!!
